Preferred Solution: "No Audio Output" on Yoga 720

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hi to everyone, with my previous pc i listened to music with a toslink on TRS cable plugged into an av receiver. Now, with the yoga 710, it seems, that it is not possible to do as well. is it that the soundchip is not able to give out digital audio signals or is it a software/driver issue? the digital audio output signal is not listed in the audio devices list. thanks for help specs: yoga 710-14ikb; i7; 8gb

Hello, I bought a Lenovo YOGA 730-13 several weeks ago and since then haven't been able to use the sound on it. It says that there is no Audio Output Device installed on it, and when I push the sound icon it just troubleshoots, but never fixes the problem. Is there anything that I'm supposed to do or missing? Thanks!

Hello everyone,I was reading something on my computer and I wanted to listen to music, but I couldn't hear anything. I thought that I maybe muted sounds but it wasn't the problem apparently. I looked at the audio icon and it shows red x. And when I move my mouse to the icon it shows that "No Audio Output Device Is Installed".   Maybe some of you know some kind of solution to this problem. Thank you.

A while ago my sound suddenly sopped working on my lenovo yoga 910. It might have been after a windows update, but i can't remember. There is a red cross next to the sound icon which says: no audio output device is installed. I have tried reintalling the correct realtek audio driver from lenovos website, but without succes. When i go to device manager I can only see one sound driver from intel, and not the one from realtek i have tried installing. I really don't have any idea of how to fix thisThanks in advance

Somehow I lost audio on my computer. It was working 2 nights ago. The speaker icon has a line through it. I went to the noaudioinput.com and am wondering if this is the best option.

Two days ago, my internet was being slow, and I had the adapter reset as per usual through the WiFi troubleshooter. The adapter for the first time caused a BSOD when doing this. So I thought "Fine, its a one time thing", I didn't get the chance to get the error message but the cause involved the adapter, I know that much. When my laptop restarted, I noticed a nice little "x" on the speaker tray icon. Scrolling over it, it told me that "No Audio Output Device is Installed." Nothing I did would fix it, including the basic solutions across the internet such as uninstalling the drivers, etc. While looking at the drivers, not all of them were missing, only maybe one or two, definitely one in the Sound, video and Game Controllers area with the name (MEDIA) in it (that much I remember, I believe it was from NVIDIA too), along with one that was put into the "Other Drivers" area, or whatever it was called, by Intel but with a yellow exclamation mark on it and it related to audio. I got the problem to be fixed by doing a system restore back to the 10th, before some updates occurred.Last night, my keyboard was malfunctioning (not allowing me to backspace, only allowing me to type in certain areas, not allowing me to use the letter "C", and telling me to backspace by hitting "Alt + LeftArrow." (And this was occurring in multiple browsers, not just one)I did another system restore and the audio problem reappeared, but this laptop is quite new, I've ran out of restore points to go back to....

Hello,  A while back I updated my laptop and the realtek audio began to work here and there. To get it to work, I would have to go into the realtek audio manager and press the 'play' button until I heard the noise coming through the speakers. It was rather annoying, but I dealt with it for a while. Recently, however, I updated my laptop again and instead of having audio sometimes, I don't have audio at all. I found a similar post in the forum, but when I went to download the link, it showed that I downloaded it, but nothing worked. I would really appreciate some help. Here are some photos.

Greetings, Lenovo community. I've had this laptop (ThinkPad Yoga 14, running 64-bit Windows 8.1) for about four years, and, for the past few months, I've been having small issues with my audio. Video files will play fine, other than them being completely silent. Strangely, though, audio from YouTube videos and (some) installed video games will play. I then decided to update the audio drivers. I found the correct drivers for my machine and uninstalled the Realtek HD Audio device prior to the installation. It completed without any issues. However, when I restarted my laptop, I was greeted with several issues. Firstly, I have no audio, period. Secondly, the computer isn't recognizing the built-in speakers or the headphone jack as being installed. And thirdly, in the Device Manager, neither the speakers nor the headphone jack are listed, and the Realtek HD Audio device under the 'Sound, video, and game controllers' submenu has been replaced with 'Audio Device on High Definition Audio Bus'. It is marked with a yellow warning triangle, and the Properties window states that it has not been configured correctly (Code 1).

I got a red x next to my speaker with the error "no audio output device is installed".  I reviewed this solution (https://support.lenovo.com/it/en/solutions/ht501860) and uninstalled and re-installed the driver accordingly (https://pcsupport.lenovo.com/it/en/products/laptops-and-netbooks/yoga-series/yoga-910-13ikb/download... I also checked for updates after the installation. While the driver worked after the initial restart, I found that sometimes it would stop working.  A few times I was able to get it to work again by just re-starting the PC.  Then it stopped working again.  When I check device manager, the sound driver comes up under "other devices". And the red x next to the speaker is back, and re-booting the PC has not helped. Please help.

Hello,My problem is this: I have an old  set of speakers such that the left speaker eventually stopped working.
Upon taking it apart, turns out the wire was just pulled away from the solder to the pins.I replaced the wire and it was good as new.
After a few months of use, (once in a while use) the left speaker "stopped" workingI later discovered that it still works, but is very very quiet.Such that, I have to set the right speaker balance to 9% and left to 100% to get the same volume from both speakers.I took it apart today, re-glued the wires back to the pins, no difference.
So I am wondering, with Dell Audio client, and my Dell xps 8700, which has a front and back 3.5mm audio jacks, can I set the balance to the front port to be my 100/9 for the speakers, and 100/100 for the back which connects to my headphones?
I took a look in the audio client, but it looks like no such option exists.Do I go looking for a new set of speakers or is there an easy option here?

A:Can you change the balance output on a specific audio jack output with Dell Audio?

I believe both jacks are controlled and connected to the same ports and software so directing one to do one thing and another to do something different isn't possible as far as I know.  Maybe someone will have a different answer, but I don't think Dell's software is advanced enough.

I have had my Thinkpad connected to a Samsung TV via HDMI cable (through a Thinkpad dock) for months with no problems. After the latest Lenovo updates (see attached screenshot file) my Thinkpad intermittently fails to recognize the Samsung TV as an audio output... it does not register as an audio device in audio settings nor in control panel, yet it does still connect to the TV as a 2nd monitor and video works fine. It seeems to alternate every other time that I boot up the computer. One boot-up it fails to recognize the TV as an audio output, then I'll reboot and it works.

I'm having a strange problem in my HTPC. Audio is coming perfectly fine out from the S/PDIF coaxial output, and it's normally connected only that way to the receiver, but now for other reasons I also need to connect it using a 3.5 mm to a small mixer. So in the sound manager I changed the output to the "Speakers", and in fact the Realtek sound manager detects that a cable is plugged into that output and shows me the dialog where it's selected. Problem is, nothing comes out.

I know it's not the 3.5mm to RCA cable because I plugged in my phone, played some music and I can hear it just fine. But the rear speaker (green) output puts out no sound at all, as I also tested it plugging headphones. On the Sound Windows panel where you can select the playback device I can see the volume level move up and down when I'm playing any media file, as well as in the Volume Mixer. If I switch back to the S/PDIF output and change the input in my receiver, audio is coming just fine.

I haven't tried the front outputs because they are not connected. The motherboard has HD Audio but the case has AC97 connectors, so I never cared to connect them because I don't use them. I know the rear green output worked at some point because I remember having a pair of computer speakers connected to it a few years ago.

This is a Gigabyte GA-890FXA-UD5 (rev. 2.1) motherboard with an AMD 1090T and 16 GB of RAM, with Windows 7 Home Premium. The installation is about two months old wi... Read more

A:Realtek ALC889 audio, audio fine on S/PDIF, nothing from rear output

I found out after a while. In the popup dialog when a cable is plugged in, I had selected "Rear speaker out" mistakenly thinking it was talking about the rear output, not the rear speakers in a 5.1 speaker setting. Changing to "Front speaker out" solved the problem.

A:Input audio doesn't work, output audio does.no obvious solution

I am running Windows 7 Home Premium on my Dell Inspiron E1505.

I have had no problems with it for several years; however, recently my computer has booted with a red 'X' on my audio and tells me that "No Audio Output Device is Installed." I checked my Drivers and my High Definition Sound and 2 Base System Device drivers have Yellow Question Marks by them. I tried to update the drivers manually but it says Windows Cannot Find Support for your Base System Device and it says my High Definition Audio is already up to date. I have also tried uninstalling the drivers and rebooting Windows to let the system automatically search and update the drivers. This too has failed. I do not have my Windows 7 disc available at the moment to be able to do a clean install.

Any help you could give would be greatly appreciated.

No sound.
Little speaker with the red 'x' appeared yesterday
I have gone through the whole update drivers circus to no avail, my laptop can't detect that it has speakers built in so it doesn't bother finding a driver for them.

This is where I am at:
- Intel Display Audio is the only driver installed for sound
- This means that sound works when the laptop is plugged into an HDMI
- When HDMI is not plugged in, the computer cannot find the built in speakers.
- I have Linux on this system and audio does not work there as well

I would call this a broken chipset, but the fact that the computer still processes audio with the HDMI cable attached is confusing me. Also, the 'audio board' for this laptop has 2 usb ports attached to it, and those both work fine.

Any help would be appreciated

Im having the dreadful "No Audio Output Device is Installed" problem on my realtek audio.

It worked some months ago, but im in no position to do a roll back. Im sure the hardware is just fine, it works with Ubuntu.

The computer is a Dell Vostro 430.
My OS is win7 64bit.

I tried the newest Realtek driver suite, the recommended dell-drivers and some basic windows-drivers. Nothing makes the "No Audio Output Device is Installed" go away.

Any help is welcome.
Ive attached my sound-related reg. I believe my realtek device is 0001.

A:Realtek Audio: No Audio Output Device is Installed

The Dell driver is required, non Dell drivers will either not work or not work correctly.

First thing, is the Integrated Audio enabled in the BIOS? (F2 at boot up to enter Setup).

Second, on Dell's (and many others) if the motherboard chipset drivers were not installed, the sound device will not work. In this model there are Intel motherboard chipset drivers. Try installing them and then the Dell sound driver. Dell Drivers

Hi guys,
I'm having a little problem with my onboard audio, having just installed Windows 8.1 (clean install). I have an Asus P8Z77-V LE PLUS motherboard, which includes a "Realtek? ALC889 8-Channel High Definition Audio CODEC" onboard.
I have installed the latest realtek drivers; R2.73 from the official website.
Now, here's my problem: when I was using Windows 7 on this same machine, I could plug headphones in the front panel connector, as well as speakers in the green back panel connector. This would give me two audio outputs in the device manager/sound list, which was pretty practical and enabled me to output different applications through the speakers or the headphones.
Now, however, there's only one output, irrelevant of whether or not I have two outputs plugged in at the same time. They appear in the device manager as a single device called "speakers" (see picture). Instead of both having separate outputs, they both output exactly the same audio.

Any solution to this?

A:Realtek HD Audio only shows one audio output at a time

Hello audiobreak,

Try going into the Realtek HD Audio Manager (Control Panel > Hardware and Sound > Realtek HD Audio Manager), then look for a setting called 'Make front and rear output devices playback two different audio streams simultaneously'. I cannot remember where this is located (The Realtek HD Audio Manager has different skins depending on the motherboard vendor), but for an ASUS Motherboard, I believe you click the Cog Icon in the top left and the option should be in there. I don't know if this will create a separate Playback Device for the Front Panel in Window's Playback Devices, but it will at least allow you to hear audio from both your speakers and headphones at the same time.

Hope this helps.

my computer's sound has stopped. I have searched through lots of websites looking for help.
I first noticed this problem when I tried to open iTunes and it came up with the message 'iTunes has detected a problem with your audio configuration. Audio/video playback may not operate properly'. I also cannot listen to music or things online either.
I have looked at my computer's device manager and can't find any catergory such as 'sound, video and game controllers', which one site suggested to try and check the sound card. I have also tried to update quicktime but that did nothing. I have also tried looking at 'sound' and under both the playback and recording columns it says that there are no audio devices installed. THis appears to be the common phrase along a problem with the audio configuration.
This has not ever happened to my computer before and I have had it for about 3 years now. It is a toshiba laptop with windows 7 home premium.
Please help guys, I am really frustrated.

A:Audio configuration no audio output devices?

If its not being detected at all in the Device Manager, it will not show up anywhere else.

When you boot up your PC, enter the BIOS (could be called "Setup") and check to see if the sound is disabled. If it is disabled in the BIOS it will not show up in Windows. If its showing as enabled in the BIOS, do a BIOS reset (to factory setup) and see if that makes a difference.

If its not disabled in the BIOS there is a chance the hardware has failed.

About 6 month's ago I reinstalled my OS and all my software, shortly thereafter I noticed I had an issue where any sound that was coming through my headphones was being retransmitted through the mic, with further testing I found that this was not actually the case but rather any sound that would be output is being retransmitted as audio in, even if I had no speakers, headphones or mics connected. I have looked at and experimented with everything I could in every sound settings I could find, but nothing has fixed the issue.

Before anyone asks, I have tried updated drivers, the only way for me to stop the issue from occurring is to mute the mic in the recording control, but that stops me from using the mic altogether.

Please Help I need to be able to use my mic without recording anything that I am hearing as well...

A:Yoga 910 - no video output

Welcome to the forum.
Is your adapter from Lenovo? Yoga 910 Platform Specifications indicates that both HDMI and VGA dongles are available but does not give part numbers. If you have a Lenovo adapter then perhaps you could call Lenovo and confirm that it's the correct one.
In this thread Yoga 910 USB-C Adapters user PhilipHendry says, "I've used this Dell USB-C to HDMI Adaptor and it works perfectly with the 4K monitor at 30hz I've got a work." Other posters on that thread report problems with other brands of adapters. It seems that the Y910 is particularly finiky about this.

I'm running a Dell XPS 420, which came with Windows Vista. I decided this morning that I was going to give Windows 7 a try, backed up some media on another PC, and did a completely fresh install.

Everything worked perfectly, I didn't even have to install any drivers. My native resolution was automatically correct, the sound worked, the internet worked, everything was dandy. It worked perfectly, and for the record, I really enjoyed it. I used it for several hours, getting used to the new features and whatnot.

I went to sleep for a few hours, and then went out for a while. When I came back, the sound had stopped working. It gave me no error at the time, it just didn't work. WinAmp wouldn't play my MP3s, Youtube videos were without audio, system sounds weren't playing, and yet, the volume was enabled and at an audible level of 67. My speakers were still connected properly, too.

I figured maybe a reboot was in order, and when I restarted, there was no sound still. Now, however, the speaker taskbar icon had a red x next to it, with the words "No Audio Output Device is installed." on the tooltip. I rebooted again and there was no change.

Using the Windows 7 trouble shooter, it says that "Hardware changes might not have been detected."

The odd thing is, this has happened to me before with Windows Vista. I wanted to perform a clean re-install of Vista, and when I did so, the sound worked perfectly for a few hours, before going out again. I would re-install Vi... Read more

A:Audio stops working, "No Audio Output Device Installed"

Hi filmtrauma, welcome to the forums.

While you have been asleep, Windows Update may have installed a new Sound driver for you which may have caused this error. Open Windows Update and click 'View Update History'....

You could try downloading the latest drivers from the hardware manufacturer, a lot are now supporting Windows 7 too..

Also, is your sound hardware plugged in (to the motherboard) securely? It's rare but i've dealt with some cases of hardware coming loose, might be worth a look. Another thing to check may be the temperature of the card, it may be getting overly hot due to a dust build up (might not be, i'm not 100% up-to-date on all sound hardware).

Hope this helps

A:Yoga 720 13" maximum output resolution

Hi zarka,
Welcome to Lenovo Community! And happy to have you here.
Looking at the Platform Specifications of Yoga 720 13" it says Max resolution: [email protected]  using DP port. And IMHO it can output [email protected] if you are using DP port only according to this. But the monitor which you have mentioned doesn't have DP input. 
I hope the above information helped you.
Please feel free to post in Lenovo Community Forums if you have any further queries!

I have a Thinkpad Yoga S1 and when I connect it to my Asus External 24" LCD Monitor via mini-HDMI to HDMI it drops connection every few seconds.  The cable is properly fitted so its not a loose connection and I checked that my video driver is up to date. Any suggestions? regardsSteve

Is there any way to get higher than 1080p resolution on an external monitor through HDMI from a Yogo 150 14-IKB? I've just bought a monitor that can do up to 2560x1440 @ 60Hz (as it can when connected to my other laptop which has a 16" screen that natively runs 1366x768, using AMD Radeon R5 graphics) but it appears that the Yoga 520-14IKB can't do so. What I've tried so far is to update the drivers on the Yoga for my new monitor, so that Windows 10 doesn't use the default PnP monitor driver, but this didn't immediately unlock any other settings. The default maximum resolution through the output is 1920x1080, which means that pixel size on the external (24") monitor is >1.5x pixel size on my laptop screen (14"). I've looked at the Intel HD Graphics Control Panel (as it runs Intel HD 610 graphics), and I can add this extra resolution as a custom resolution, but the monitor claims the signal is out of range when I try the 2560x1440 (60Hz) that I can get from the other graphics chipset. Is there anything else to try?

Actually, though further inspection on my 15.6" laptop, the output is downsampled in software before going through HDMI at a 1920x1080 resolution, which is what the monitor can use, so it looks like it might be a driver issue rather than anything hardware related.

I've read dozens of topics relating to these questions yet have found no answers. I'm looking for a software solution NOT hardware.

1. How can I record the Windows 7 Text 2 Speech voice?

2. How can I playback the recording through a program(WMP, MPC, etc) and have it go though the mic instead of speakers? Pretty much I want the text to speech to act as my voice for a mic. I don't care if there is no speaker output while this is happening.

A:PC Audio output to Mic

A microphone jack is an INPUT, it's not an OUTPUT.

But, if you have a "System Mixer" (may be called Stereo Mix or What You Hear) then you can record what you are hearing on the PC speakers using a program such as the free "Audacity". Record with Audacity and save the file as either wav or MP3. You can then play it back with any media player.

In Device Manager (right-click Computer and select Hardware) you could try rolling back the driver for the sound card but have a look in Control Panel first as it may just be that SP1 has reset sound output settings ...

Hi I have recently done a windows update but due to this I have no sound playback from my computer, when I hover over the sound icon I get this message 'No audio output device is installed'
On this I updated the drivers with a manual search and then manual, this didnt help.
Next I restored my pc to an earlier date when the audio was working, also didnt help.
I have checked that sound is enabled in the BIOS, nothing.
Please help as I cant even reinstall windows 7 due to my DVD drive also being broken.

A:No audio output


Best thing to try is do a system restore to the date previous to your update, if that produces sound then do not update your windows update with that update. It's not well known but there are updates than can mess with your system settings (not intentionally)

Let us know if that works

Good Day,

My problems is that no sound can be heard from my laptop. The volume is there. When I play a music file i see the green bar going up and down (in the sound bar). The correct Device is selected as default device in Sound Options. I can get the sound back by disabling and enabling the Audio Device in Device Manager, but sometimes it requires a restart so it's kinda cumbersome.
The last thing I did was install an update for my Video Card driver.

My Laptop is Alienware M17x R2
Specs are,
Processor : Intel Core i7 CPU Q 820
Memory : 8192MB Ram
Display : ATI Mobility Radeon HD 5800 series (HD 5870 Crossfire)
Sound : Speaker / Headphones (IDT High Definition Audio)

A:No Audio output?

What computer do you have? Is it branded such as HP, Compaq, Dell, etc? You could try reinstalling the sound drivers after downloading from the computer's manufacturer website. Or do a repair install of XP if you have the xp cd.

Before I left the house this morning, I played a song on iTunes. When I came back, the only sound that would come from speakers (and a pair of headphones I have lying around) is the system beep (double clicking an icon in My Computer or hitting a key on a message box screen). There was supposedly brownouts across the area, but my computer was on standby today and the speakers were the only thing affected. I have tried everything with full volume and nothing works. I have a WinXP P4. PLEASE HELP!!!

I'm unable to receive TV sound from my TV in Windows 7 AMD HDMI output line. Although the jacks are plugged in to both TV and PC the display box indicates the line is disabled although I've enabled it. I also checked for an updated driver and replugged lines without success. The PC speakers do reproduce audio. Please advise
