Dell XPS 15 9550 Crackling Noise coming from speakers when plugging and un plugging power supply.

Q: Dell XPS 15 9550 Crackling Noise coming from speakers when plugging and un plugging power supply.

I Got my XPS 15 9550 Build Date Dec-16-2015 Bios Ver 01.00.07 4302.13 UEFI
The fault I was able to find so far that is disturbing issue.
Condition1 - "When pressing brightness keys F11-F12" (little crackling distorted noise from speakers)
Condition 2 - " When music playing out of speakers also at sometimes can hear crackling noise coming" ( like speakers can't handle the frequency properly)
Condition3 major one - "At the time of plugging in power supply in or out of laptop." When video/audio/u-tube playing I can hear short crackling noise lasting about (4-6 seconds) output sound also gets distorted coming from laptop speakers same results happening when using headphones except crackling noise less noticeable sounds becomes more distorted like a tape that about to get jammed.
So not sure what's goin on there I have latest Audio Realtek driver installed & Bios 01.00.07.
As far as power laptop came with 130W so crackling happening even with 130W also I have Precision m3800 laptop that use same power source try that as well same results so it is not defective power supply it is something else
Makes me believe that issue with speakers hardware picking up some kind of interference (or crammed to close) or insulation are very poor.
Will be returning that one for full refund as this one I got for gift cant give it like that.
but I have ordered 2 so will try another one soon.
and also CPU throtling as mention still not happening when plugging power source.
to sum up the major issue I experienced is the speakers as very poor sound with crackling noise here and there. power supply (plugging /un plugging while audio playing) cause most cracking noise.
plugging headphones in and out while sound is playing sometimes becomes unresponsive crashing.

So the speakers and sound quality output are very poor on this one.
besides that seems to be good
Feed back would be good.
Did anyone experience similar issue and if yes what was your resolution possible fix (hardware replacement / drivers ect / settings adjustments)

HiI've got a brand new dell xps 15 9560 for 2 days. I was ready to install 3 pending updates, but after installing them I'm experiencing troubles with sound. When nothing is playing, or when I just lower or raise audio volume, short static noises can be heard. 
These updates were about the BIOS, which is now version 1.5.0 from august 30 apparently (just giving as much information as I can - because I've noticed BIOS updates to pop up in some of the threads about audio noises).
Also, I'm a bit dissapointed that when I plug in external speakers via the jack, my computer will lag a couple seconds, and will not respond as fast as I'd like from this computer when I click 'external speakers' when it prompts me, asking what kind of audio input I plugged in.I've browsed the forums for a solution, I've tried updating the drivers - which were up to date. I've tried resetting sound bit quality, but it throws a warning so I didn't dare messing with that. I'm also not messing with all these dell apps since I'm a brand new dell user, I'm not that experienced with what I can safely remove and what not So I'd like a solution for the crackling sounds, and if possible I'd like to know if I can safely disable the maxxaudiopro promt when plugging in external speakers. I don't need presets for headsets or external speakers - I'll be fine setting sound volumes by myself if that's what this is about. If I can safe... Read more

I just bought a Toshiba Satellite with Windows Vista.

One of the few issues I have is when I plugin my headphones to listen to music, sound still comes out of the Laptop speakers. When I turn down the volume on the laptop, the volume on the headphones also comes down.

How do I change the setting so that I can listen to music on my headphones without music coming out of the speakers..?

Hello all,

I built an Athon 64 3000+ about 2 1/2 years ago, and had no problems; then one day in the middle of an e-mail it up and shuts off on me, refusing to turn back on. I've detached every piece of hardware from the motherboard, including the CPU, with no effect.

With just the 20-pin power supply connector, the fans run, there is power to the motherboard, and the motherboard lights inform me that the CPU is not posting (as one would expect it not to with no power and now no chip). However, the minute I plug the extra 4 pin 12V supply in to the motherboard, the whole thing shuts off. The 4 pin connector reads 12V when the 20 pin connector is plugged in.

Any ideas? The MB is an MSI K8T Neo. I didn't jostle it before turning off, I don't think, and a 300W power supply I have leads to the same effect: the fans run with the 20-pin connector in, but as soon as the new PS's 4-pin 12-V supply gets plugged in, everything shuts down (no fans, no MB lights).

Thanks in advance for any help!

A:Plugging in 4-pin 12V supply causes power to shut off

At the least you must try another power supply. It could be any rail, or a short, that is causing it.
And if it's not that, I would suspect the CPU or motherboard died.

I have a sony vaio with xp home edition. I have a diagnostic program that I can plug into my car to see how it is running and pull codes off the ecu. When plugging the car into the vaio tonight I heard a quick 1/4 second whine like zip sound and then NOTHING! I brought the laptop in to look at it looks fine, smells fine. Plugged it in NOTHING! It's like there is no power getting to it at all. Does anyone know what happened? My guess would be some type of surge through the cord connecting the car to the computer. CAN THIS BE FIXED? Please advise! I need to get this up and running immediately... THANK YOU!!!!

When I plug a power cord in, the power light instantly (almost) lights up, whether or not I've pressed anything to try powering it up. When I DO press the power button, nothing changes. Nothing sounds like it's running at all. Someone suggested moving the RAM around, so I placed it in a different slot, but that didn't change anything. This was a frankensteined computer that was given to me, so I can't even really provide much in the way of specs. It's an IBM ThinkCentre S50 (shell anyway), but appears to be loaded with a 40GB Seagate HDD, Intel P4, 512MB RAM, and an AcBel power supply. In case this matters, and I don't know enough to know or what I would do about it, but there are a few open plugs for power. The motherboard has a couple plugs running into it, but one still open. The HDD has two empty plugs, but one plugged into it. I would have no idea how to play around with the power supply. Not to say that's the problem. Thanks for any help.

A:Computer shows power light upon plugging in, but no boot, noise, or any startup

It could be the power supply (officially called a "PSU" or Power Supply Unit) that's faulty and needs repalcing, but you were right not to go messing with it as even a faulty one can give you a nasty shock from the power that's stored up inside it. I've worked on fixing & upgrading computers for many years, yet even I draw the line at changing a PSU. I let my local PC shop do it for safety reasons, plus I believe in supporting little independant PC shops whenever possible.

Hey Guys...

So my Packard Bell Easy Note MX37-S-200 has suddenly started making persistent " Crackling " and " Popping" noises from the moment I boot it. The noise is coming from the speakers and the sound is now distorted. I have very recently got it back from the repair shop after having my AC jack replaced... I would really like to rule everything out before I start pointing fingers at the repair guy

Things I have tried - Disabling sound driver - Noise was still there and laptop just installed it again.

Running avast scan through it - Scan picked up nothing.

Played with the sound setting - Nothing changed noise still there.

Plugged in PC speakers - Noise still coming from laptop but sound came out of the speakers fine.

I have noticed also that when the laptop first starts up the noise is louder and more spaced out. I'm wondering maybe whether it is the fan? But I don't no why the noise would be coming from the speakers.

Would really appreciate any help
Thank you

A:Crackling noise coming from laptop speakers + sound distorted

My guess is that based on the information provided that the wires for the speakers have either been damaged or crossed in some way where they are touching something they shouldn't causing distortion. My advice would be to take it back and tell them whats going on and make sure to have them fix it for free if they opened it and caused this problem.

When I plug in my usb mic, the sound from my speakers or headphones shuts off automatically. This guy had the same problem but I did not understand what DvK01 was trying to say.


"there shouldn't be any need to to spnd a lot of money on any external sound card
what happens when you plug a USB microphone in, is the OS thinks that it is a complete USB sound card and turns off the internal sound system
your only cure is to either use a USB combined microphone & headset or use a Mike plugged in to the small mike socket - (What does this mean?)

You might find that the sound settings is automatically switching the sound to use the mike as a communications device, not as normal input
But it isn't uncommon for a cheap USB sound device.microphone to have such poor drivers that are only really intended to be used for communications purposes ( Skype or other VOIP systems) and you haven't got a passthrough set up so mike & sound cannot be used at same time in normal use"

A:No Sound from Speakers when plugging in USB MIC

Are you saying that I will not be able to hear sound from my speakers using this mic? Is an external sound card even an option?

also, the mic doesn't seem to be recording at all and I don't know why.

When he said usb combined headset, there is a headset jack on the mic and I can hear through that but I still need to get my stereo system speakers to work so that I can have the music playing in the background while I sing through the mic.

Hello folks.

I have a high pitched noise coming from my power supply. It happened recently, and it's been lightning around here to boot. It's on a surge protector, but obviously we know that doesn't mean it can't still be hit.

Anyways, I can hear it fine but my dad can't. Before the tumor jokes start, my little sister can hear it as well, so evidently we both have tumors. I ended up unplugging everything from the power supply, including the motherboard, and turned the power supply on and off, and the noise only started when the power supply was turned on.

It still works, but it annoys the heck out of me. Obviously I want to replace it but I'm not sure if I can get an RMA. Is there any risk running it like this?

I got a really horrible LogiTech Headset Microphone that I got only yesterday, and the first time that I tried to use it it doesn't record my voice AT ALL, even when I have done basically EVERYTHING it told me to do in the manual.
The Microphone plays my voice through the speakers when i'm talking into it, but it doesn't RECORD my voice, which is what I want it to do.

Now, I have a different problem. After I took out the microphone there is no sound coming from my computer speakers. I don't know what to do.
All sounds from my speakers are up on full blast. Nothing is muted.
The sound only works through my stupid LogiTech headphones. But the sound is all echoey.
And my speakers are most certainly NOT broken. They worked fine before I plugged in this stupid microphone that doesn't even work.

I was trying to get my microphone to record for around 35 - 40 minutes, but it doesn't do anything on any programs!
I sure hope I still have my receipt for it! But it doesn't solve the speaker problems :(

A:No Sound From Speakers after plugging in bad Microphone

Hi WeeGee and welcome to TSF

On the recording your voice part, go to control panel and pick Sound and Audio Devices, pick Voice tab, under voice recording, pick volume. At this point, pick the options tab and make sure the Sterio mix is checked. This will add a control the the volume group that you will need for recording.

On the speakers not working after removing the head set. Note this, when you plug you headset in, the plug opens the contacts to your speakers so they will not work. When you unplug the headset, the switch contacts in the plugin port is supposed to make contact, thus restoring volume etc back to your normal system. Try pluging and unplugging the headset to get that part working again.

Be sure that you are using some sort of recording software to get the recording to work. Windows has a short one that you can use, or other recording software might be needed for long samples.

Hope this works for you,

Hey fellas,

This happens on WAY to many cases I come across. Almost every case from Codgen seems to have this issue, as well as it has happened a couple times on my own case from A-Top.

When you go to plug in a headset or speakers, as soon as the metal from the stereo plug touches the metal from the FRONT audio jack, the PC instantly restarts.
It's obviously a power issues, bad ground, whatever. There is no BSOD or anything like that. Just instantly restarts. It bugs the heck out of me cause I'd really like to use these front jacks. It doesn't happen on rear jacks.

Anybody else have this happen on their case? I'd like to know if there's anything I can do about it. Perhaps add something nonconductive between the jack and case? Or put a resistor somewhere? Why would plugging in a headset cause a reboot? I'm no electrical engineer. If it's a ground issue, can I change the case in some way to stop this?


A:System restarts when plugging in headphones or speakers

You know, another thing that is odd about this issue is that, as far as the case is concerned, I can "zap" it all day long and never get a restart. That is, if I have static buildup and touch the metal somewhere and get zapped, it doesn't ever restart. But only through the audio jack. So this obviously limits it to the audio subsystem.

Of course, half of it is just cheap cases, but still, there must be something that can be done.

I have a three port SATA controller PCI card, into which I successfully ran two 500GB SATA HDDs. One of them had the old-style 4-pin power socket (PATA IDE drives), while the other needed an adapter cause it was a SATA power connector only.

Anyway, all was fine until I purchased a third SATA drive and plugged it into the remaining slot, situated on the out-facing metal plate of the controller card. This one also needed a power adapter for my old-style PSU. The new drive worked fine, but the second of the two original drives fails to load.

First of all, am I right in guessing that it's not a power issue? The reason I think this is because in the past when I've plugged an unpowered drive into the SATA controller, it renders the SATA controller useless, and none of the SATA drives appear in My Computer. So, because I can get two out of the three drives to work simultaneously, am I right in thinking that it's not the power?

Is there some sort of SATA BIOS that I need to tap into to enable something? How is this done?

Any ideas?

A:Solved: SATA HDD #2 fails to power up after plugging in HDD #3

This is so odd. I'm running Windows XP SP2 on Dual core INtel with 1 gb memory.

I've installed a front USB panel that has 4 ports in front and 2 more on the PCI card which it's attached to. (added on peripheral).

I can deal with the "this device can run faster if plugged into a 2.0 device" but what is really frustrating is that if I plug in 2 or more USB devices. At least one of them won't work.

This computer is in my family room and wirelessy networked to my other computer in another room. I use a Motorola USB device to connect for the purpose of printing stuff off the printer in the other room.

If I have too many USB devices plugged in - there doesn't seem to be enough power to allow the wireless connection - resulting in not being able to print.

This isn't the only issue. I have some software that requires the USB "key" in order to work. If I need to use that software using the "key" and then I need to print something from that particular software to the remote printer - I have to save it to my desktop firsti - then disconnect the "key" and then I can print.

Do I need a bigger PS? I have a 500W now. I thought that would be big enough. Perhaps the USB issue isn't related to that at all? Is there some way to regulate how much power is assigned to USB devices?

I have an Acer Aspire E15 laptop, I've been using it with Windows 8.1 until I did a clean install of Windows 10 recently. Normally, when I get the warning notice that I have 10% power left, I plug in the power cord and continue work.  But now when I plug the cord in, it turns off the screen (goes black). I still get audio but no video. If I unplug the cord, the screen comes back. What's going on? I've never had this issue with Win 8.1 or any other OS version before.

Check your power saving settings (Search for Power Options, then change the plan settings) and make sure the 'turn screen off' option isn't set somwhere weird when running on AC. Also make sure the brightness isn't set to zero.

I have a Dell Vostro 1400 running Vista Home Basic and have had two periods in the laptop's existence where it would mysteriously freeze. You could see everything on the screen, and the power lights were on, but it would not respond except to a hard reboot by holding the power butting down for 5 seconds.

I am going through one of those periods now, and have discovered that the problem happens when I am either plugging or unplugging the AC power adapter, but don't know why. I have been all over the web for a solution, and while it does seem I am not alone with this problem, I have not read a sensible solution yet. My favorite bad answer is "don't unplug your laptop when it's on."

So, does anyone know what it could be? I wanted to look at system logs, and so went into the Event Viewer not even sure what to look for, but didn't see anything that looked like a likely culprit. Please help!


A:laptop freezes when plugging and unplugging AC power adapter

being a member of the Dell Community Forum, I looked there and found this

A lot things happen in Windows when inserting the AC power adapter.

To check if it's a classic CPU lock-up: repeatedly press capslock. If the capslock light doesn't change, there's no live in there.

Assuming the CPU is locked up: It's possible there's a log entry in the system log just before the AC power adapter is inserted. These entries give clues where to look, just before things went sour.

Next try to reproduce it in Safe Mode (press F8 when Windows start) If it's also in Safe Mode - try running an alternative OS (no need to install)

If the problem also shows up here - most likely it's a hardware issue.

Otherwise it's a windows issue - might be driver related.

the "alternate OS thing is a link on the forum web site. Click here to go to that site.

Can I damage my motherboard by plugging in the case power button connecter backwards? Neither my case nor my motherboard specifies what is negative and what is positive.

Can I damage my motherboard by turning it on with nothing in it? (Ram, processor...)

I attached a picture of my current set up and a scanned diagram of my mobo manual.

Current set up:

A:Damage mobo by plugging in power button backwards.

The case power switch is just a switch which shorts the two pins on the mobo via the leads and case switch. Short answer : no it doesn't matter which direct the case power switch leads plug into the mobo.

Can you damage the mobo by turning it on without RAM and CPU...no, but why would you want to? Really destroyed RAM or CPU which looks like a short (electrically), yes! time to buy new mobo. But no RAM or CPU is just an open circuit so you'll just hear alot of beeping from the BIOS.

A:Computer Auto turns on when plugging in the power cord

It might be the power supply, a lot of the Gateway and eMachine computers have problematic power supplies. See if you can borrow a power supply, say from anther computer, and try it.

As long as the power cable is plugged in in my notebook the brightness of my display is fine.

But when I plug it out and use the battery the brightness becomes suddenly darker.


How can I prevent this switch-to-dark-screen?

I found no corresponding option in the power plans


A:Notebook display brightness low when plugging out power cable?

Try going to the Power options and then click Change plan settings for your power plan then in the next window under battery at the bottom is a adjustment for brightness. Be sure to save changes one done.

Hello, I have a Y510P notebook and I am having some problems with it. Once I was playing on this laptop and it suddenly it turned off. The power cord would make a weird noise and it wouldn't turn on. After a while it started to work normally. It was probably a high voltage spike in my house, since we already lost a cellphone. After that I notice that the laptop would turn off, as soon as I plugged the power cord. I ordered a new power cord and battery, but this issue is still happening. Anyone has an idea? Thank you!

Hi Tiagoramosleite,
Welcome to the Community Forums. 
You can initially start isolating the issue using the power checkout guideline (page 21). 
Try to notice anything on the DC port like bent pin , unusual appearance / marks or smell of burnt . 
Would any led status light (page30) still be lit when plugged in. 
It would be best to have it further checked for further isolation for dc in port issue against failure on the systemboard itself with nearest service center or call in technical support for further recommendation. 
Update us how it works best for you.

Hi All! Been a while since I've posted, but sitting here reading other's posts, I almost forgot why I logged in!

I have a weird problem with my computer.....a little background:
I didn't turn the computer on for a LONG time....perhaps a year, so one day, I decided to boot it up and it won't boot past the post! So I replaced the MB battery, checked the power supply, replaced the memory...and it booted. But then, I turn it off, and it won't boot again...same problem with it not booting past the mem. post. So being that it was an old computer, I figured I'd just build myself a new machine and use the hard drive as a slave. There are programs on the drive that I want to use that I cannot replace! Well, I tried doing that, but the new computer won't see the drive....it won't even boot with it plugged in. So....

I take the hard drive to another machine that I know works fine, and it boots. Problem solved....so I thought. I turn it off, and try and turn it back on.....nothing.....no beeps, no post....nothing. So I tried changing the power supply, and plug all back in, and it boots. Turn it off, nothing. Long story short, if I unplug the motherboard power cord from the board, and plug it back in, it boots, but if I turn it off, I have to repeat the motherboard plug thing to get it to boot again. I have had the drive checked for viruses, and it's clean.
I have to admit, I am stumped! Any ideas? Any suggestions would be greatly appreciat... Read more

Hello i've had my pc for over 3 years now and only just discovered this forum!

My pc is only used as a touchscreen jukebox, however it makes an awful crackling noise from the pc speakers (sometimes louder than other times). This has always happened, seems quite mad that i've only just decided to resolve the problem!

Any ideas?

A:Crackling noise from the pc speakers

Can you please tell us which PC model do you have? Do you use original preinstalled OS version?
> This has always happened...
How to understand this? Have you noticed this issue from the first day?

Have you tried to test sound quality using headphones, different ways to test internal speakers, anything?
Please post a bit more information. This can help us to understand the problem.

XPS 9350 - Windows 10
Can I make Dell Audio (or something) automatically route the sounds to my headphones when I plug them in?  I didn't see any option within the Dell Audio menu to toggle that option.
I do quite a bit of work in my school's library, meaning I need to be quiet.
The problem is that when I plug in my headphones, I have to wait for Dell Audio to pop up and then I have to confirm my selection of "headphones with microphone" before any sound will go to them.  Only then will the sound go to my headphones.  While I do this, my computer starts dinging and beeping all the latest notifications for anyone nearby to hear, until I do the confirmation.
To make matters worse, if I plug in my headphones on the Windows lock screen and then sign in, the Dell Audio pop up never comes up; however, I still get the Windows notification center give me a notice, but it is non-interactive.  So then I have to unplug the headphones, wait for all the alerts saying that I unplugged something to go away, then plug them in the again.  If I don't wait for the alerts to clear, the Dell Audio selection windows won't load.  Again, the dings and beeps are going once I sign in and do all of this.
Of course, this is all provided I didn't mute the audio before I closed the lid the last time I used it.

A:Dell Audio - automatically switch to headphones when plugging them in.

SOLUTION: the pop up menu isn't clear.
If you toggle the option at the bottom saying to not pop up each time something is plugged in, it will just automate whatever it is you plug in (at least I can confirm that for 'headphones with microphone').
The way the radio button is phrased, simply sounds like it's just meant to turn off the pop up and nothing more.

Hi. My power adapter cable recently broke, so i replaced it. But I accidentally got the 90 W one when I was meant to get the 130 W. When I plugged it in, for some reason, i couldn't access the internet or my home network anymore.

A lot of the network adapters in device manager have exclamation marks next to them:
I tried updating the wireless device driver, but it didnt change anything.

Any ideas what I might be able to do to get it working?

Yesterday evening, my Z50 had been working normally. I put it on stanby over night, but it was running this morning (with the lid closed). I have observed this behavior on multiple occasions, so I wasn't worried. It seems that Windows sometimes wakes laptops in standby to update overnight. In any case, opening the lid, no image appeared. I closed the lid, computer did not go into standby. So I shut it down and rebooted it by prolongued pressure on the power button. Screen remained blank. Did this a few times, no change. External Monitor is not getting HDMI signal at any stage. Keyboard is unresponsive (caps-lock and num-lock LEDS do not toggle). In fact the only way I can even tell it's running is because the power led is lit and the fan is working. Oh, and it gives a single sharp beep when I plug the power in or out (both ways produce the same beep). That's the only reaction I could get from it. Things I tried, all without any effect whatsoever:Running only on PSU without battery. Running on different PSU without battery.Running on battery without PSU.Unplugging PSU, removing battery, holding power button pressed for a minute, putting battery back in, booting.Booting using the NOVO button. Can't see any way for the usual household remedies like system restore or BIOS reset, as for all I can tell the fan is the only thing even running in there.Currently just leaving it running to drain the battery, but I don't really see what that could accomplish.
