Sound Card and HDMI port stop working at same time

Q: Sound Card and HDMI port stop working at same time

I have a Lenovo thinkpad yoga 14. All of a sudden my HDMI port does not work and my system says there are no audio devices available. When I go to device manager, the sound, game etc option is hidden. I updated my audio driver, in instilled The Conexant audio driver and rebooted my computer, but now it is not getting reinstalled. Every time I try to reinstall that driver, it says no audio device found, cannot reinstall. I?ve even reinstalled windows but even that does not work. Need some help badly!!

Hi there, My sound is not working. I only have a HDMI Sound output. However, I don't have any HDMI Output in my computer. I reinstalled windows a couple of times lately, but i don't know for sure if thats the problem.
Right now im using Windows 7 32-Bit, My hardware specs are: CPU: Intel Duo 2 Core. Graphics Card: AMD ATI Radeon HD 3800 Series. Any help or such will be Very much appreciated

A:Sound not working, Only have HDMI Sound Output, But no HDMI port in PC

the HDMI sound is most likely off your GPU but that series seems to not have a HDMI port so that is odd. If you can make sure your onboard audio is on in your BIOS and also run the tool on this page so that you can update all your system info for us. System Info - See Your System Specs

I have the same problems. Today I updated the Bios of my HP probook 650 G1 to version 1.39 from 1.36
After that my DisplayPort is not working anymore. The external VGA port is working fine.
There is no way to downgrade again. Error message at the end of that downgrading process tells me the digital signature is not valid or the image is damaged. So please HP, fix this problem in 1.39 for all users.

TLDR: Graphics card and wlan card randomly stop working!!

I've posted this on other forums so far no help . so heres my problem. I use my computer on average 3-10 hours a day. I usually play games or im surfing the net. now sometimes my wlan card and my graphics card just stop working. they both dont appear in the device manager, I cant plug in my monitor through the graphics card coz the screen just stays black, and the wireless internet icon on the bottom right of the windows screen just says "no connections available". Im not 100% on this but it seems like this occurs after playing games for long periods of time im pretty sure the games I play arent too heavy for my system (empire:total war, skyrim etc). I took my pc to the repair shop before and everything was working fine when they tried it. I dont think its a problem with the wlan or graphics card coz sometimes they work perfectly, then suddenly they just stop working. when this happens it usually gets fixed when I wait for a day, open up the pc and clean everything then perform a system restore. I have no idea whats wrong. Is everything compatible? could it be overheating? could the motherboard be faulty? Its very unlikely that both these parts just stop working at the same time.

Noteworth:
-Sometimes when the wlan card stops working, the light on the card itself isnt lit up, but sometimes it is.

-These problems dont always occur at the same time.

I was having problems with Windows Themes and aero not working, and finally fixed that by updating drivers. The themes problem is fixed but now I cannot display my laptop on my TV through the HDMI port. Any ideas?

Update: When I push the connect button, the screen goes black like it always does when first connecting, and then I get the pop up saying I'm not using the resolution for the clone displays configurations, like it used to do before the update. I've tried rebooting, and also disconnected and connected the hdmi cable from my adaptor and still nothing.

I've seen a number of computers where the addition of an Add-in Video card automatically disabled the onboard adapter. The only thing that worked to restore the onboard adapter was to remove that Add-in card. You may want to consider getting a different Add-in card that has 2 HDMI ports. Or if your motherboard has 2 PCIe X16 slots get a 2nd matching card.

Hello,
I have, as I see it, a very unique problem with my computer.
I turn my computer on, and sound works, I can turn on winamp, play music etc.
But, after random amount of time, my sound driver just disappears, when go to
Control Panel and Sound and Audio Devices, it says I have no driver/sound card.

Funny thing is, when I open winamp at the beginning when it works, it continues to play music even when it already says I have no sound, I can even add more stuff to winamp, but ONCE I turn it off, It wont open again because I have no sound drivers!
The amount of time before this happens varies, once it was hour and a half, but not it was only 15 minutes. Of course, Im still listening to music, because I havent turned off winamp yet (although, any other program I start after the malfunction, sound wont work with it).

I tried to reinstall my drivers, but I couldnt find a way how to remove everything from Device manager under "Sound, Audio and Gaming Devices", but nothing changed. When I removed what I could, windows found it as new hardware, but didnt want to install new drivers since "the latest possible version is installed". Sound of course wasnt working, until I installed drivers I downloaded from the net, but then it just returned to where it is now.
Also, right now, device manager tells me everything runs ok, but "Sound" in Control Panel says I have no drivers.

A:Dell Optiplex 3040 cannot use both HDMI port and Displayport at same time?

Optiplex 3040 onboard video out ports = HDMI, DP
A computer HDMI out port cannot up convert to a monitor DP in port via a straight cable. What you bought is designed to do the opposite; down convert a computer DP out to a monitor HDMI in port.
You would need to add an HDMI to DP Active Converter.

So, the other day I decided to finally bring my parents into the 21st century and show them the wonders of HDMI... They were amazed. Anyway I plug the cable in and everything goes swimmingly. Until someone (my mom) decides that she wants the TV back to normal. So instead of switching the input on our multisystem TV, she pulls the HDMI cable (quite harshly) out of my computer, by the cable not the plug portion. I'm not sure what she did or how she did it... but my computer stopped reading its own speakers. I freaked and restarted the laptop. It came back on and it read the internal speakers again. Everything seemed okay, until yesterday when I tried to plug the HDMI back in. Now, it wont read the HDMI cable for audio. It transmits the picture, but the sound doesn't come out of the TV it comes out of my computer. I tried going to the speaker tab and opened the mixer, nothing was muted. I opened the device manager and it said HDMI audio was installed, opened that up and it said the device was working properly. I tried opening up the audio window to see if I could manually switch to HDMI and the option wasn't even there. I plugged in my headphones and they work just fine. I'm at a loss here. I'm beginning to think a pin was pulled out along with the HDMI cable the first time. But I don't know if its possible to replace just the HDMI port... Gah... Help me please...

Hi all,

I've just recently got myself a new laptop (specs at bottom of message) and took it around a friends house and plugged it into their HD TV via HDMI - all worked well, the laptop recognised the TV straight away, optimized the display and away we went.

A few days go by and I decided to upgrade my own TV from an SD to an HD TV (Bush BLED24FHDL8) yeah I know cheap as chips, but it's going alright so far ... well except this problem pmsl.

Within 5 mins of setting up the TV channels I decided to plug my HDMI cable into the laptop and then into HDMI 1 slot on the back of the TV, I changed the input of the TV to HDMI 1 and.... nothing.

Going into the display settings of my laptop didn't show a 2nd display, so I changed various settings trying to get it to recognise the tv, but nothing, still no signal showing on the TV, and nothing showing on the laptop.

So I changed over the cable to the HDMI 2 slot on the TV etc and still nothing on the laptop, I fiddled with the settings again and still couldn't get the laptop to recognise there was a 2nd display, nor get any signal on the TV.

As a last resort I unplugged the HDMI cable and tried the VGA cable I have - and this decided to work, although no sound as I didn't have those cables plugged in.

When I plugged the VGA cable in, the TV and laptop recognised each other straight away and I didn't have to do another thing.

Are you running more then one monitor at a time? If you are then you need to right click on your desktop and select "Screen Resolution". Then find the TV on the display device drop-down menu. Then check the box "Make this my Main Display".

Using an XPS Studio 16 recently the HDMI port I have been using to connect my laptop to my speakers has been acting up. After connecting to my speakers the output automatically shifts to the speakers, however there is no audio. When I open the volume control panel it shows audio output being sent to the speakers. So far, the only thing that has resolved this issue is a restart, however after restarting no settings changed from the time when the issue occurred.

I have made sure my speakers are searching for input from the port I have connected it to.

Any help would be appreciated. Also, tell me any information I need to give you in order to help you, help me.

A:HDMI Audio Port Showing Output w/ No Sound

When using HDMI, the HDMI needs to be set as the Default Audio Device in the Control Panel/Hardware and Sound/Sound Panel. If the "Speaker" is set as the default audio device there will not be any HDMI audio.

Yesterday, I bought a 10m HDMI cable and I plug it from my TV to my CPU. Everything was fine. The only thing was one of the games which requires Port COM1 and COM2 could not access.

I tried disabling the HDMI sound and it worked. Is there any way to change the COM port for the HDMI sound? I tried going settings on Windows and could not find any.

I just need the sound because it's a music game, from the Arcade. Everything was perfect before plugging my computer to the HDMI.

Hi there,Can someone help me?I've had my all-in-one for about two years and never tried to use the HDMI port. Only now that I bought an LG ultrawide monitor (to use as a second monitor) and it doesn't work. It doesn't even detect/recognize the monitor when I plug it in, but the monitor works fine with my laptop computer. What can I do?

I recently bought an HP Envy m7, and I setup an external monitor. I recently had a BIOS update, which I think broke the HDMI port. I connected the port to a projecter, and it still does not get any input through the HDMI. I've tried multiple cables, and none of them work. My monitor I'm using is an LG IPS Flatron monitor. When I plug in the HDMI, it tells me it's not receiving anything to diplay. I've used Windows Key + P to switch it to extend mode, but it doesn't work.

I have a Dell Inspiron 720 with an HDMI port in the back. I have been using it with my Samsung TV to watch movies on. Now it no longer works. I ordered a new cable but it keeps telling me to check power supply, cable connection, and the make sure it's on the right setting. I have 2 hdmi ports on the back of my TV but still come up with the same error condition when I switch them. It appears the port in the computer is not working anymore. I have tried everything but nothing works. I am running an ATI 4200 which is on the motherboard. Can this be fixed or would I have to buy a new graphics card to get it working again. I did swap the cables but still get the same results. Does anyone have any ideas because I have run out of them???

A:HDMI Port not working anymore

The only way to fix it is to buy a new motherboard, do yourself a favor and buy a new video card instead, Dells are not worth fixing. But if it`s under warranty well then that is a different story.

If that`s a laptop then your ONLY option is to replace the motherboard, very simple to do.

EVGA - Products - Graphics

MSI USA - Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more

What keeps telling you to check the power supply ???

Hello HP community, I have a HP 15 TS Notebook PC and the HDMI port is not working. Yesterday (9/17/2016) it was working just fine. I had my laptop connected to my TV via HDMI and it working. Today my computer did an update and after the update my computer did not read the HDMI cable. I am not even sure what the update was for, but I turned it off this morning and it updated and then updated again when I turned it back on later today. After the update the computer does not read the HDMI cable. Everything else works fine. What should I do? Thanks!

Hi all, I recently bought a HP Envy desktop 750-103a but can't get the monitor to work using the HDMI ports 0 and 1? I have tried to use the playback devices to recognise it but I don't seem to be able to get anything. Could someone please assist me, I'm not sure what to do. Thanks Rick
