Windows 10: system audio output problem

I am having difficulty with sound output via hdmi. It is not getting to the display via hdmi. I have replaced/updated drivers, rebooted several times, and the sound meter shows activity but cannot get sound from computer to display. I do, of course, get image. This happened several years ago and I figured it out. But I can't remember the solution and have tried all the troubleshooting prompts.

No audio output device

Hello!
I have a common problem: my Windows 10 has No Audio Output Device.
System configuration:

• Lenovo Legion Y520-15IKBN (laptop)
• Windows 10 Pro, version 1909, build 18363.535;
• Current updates;

Device manager shows these audio devices:

• High Definition Audio Device (driver version 10.0.18362.356)
• Intel Display Audio (10.27.0.6)
• ASUS Xonar U3 (10.0.8.2164)

i.e. the problem persists even with an external (USB) audio device, recognized by the system.

I performed a sanity check on this issue. Sound works when I boot into Ubuntu live. Therefore, it is not a hardware problem, and is indeed a Windows problem.

Solutions that have not worked so far:

1. Audio troubleshooter (issues found: check audio device, nothing else)
2. Rolling back drivers
3. Uninstalling audio devices
4. Uninstalling any audio-related devices, incl. the likes of bluetooth speakers
5. Updating audio drivers (from both built-in drivers and from manufacturer's site)
6. Installing a generic audio device (installing a generic USB audio device does not succeed, and installing a generic Realtek device resulted in a BSOD)

Do you have any ideas for fixing this?

 

No Audio Output Device is Installed

Hi,

You will need to select Windows 8 from the drop down list while installing the driver in compatibility mode.

I would suggest you to try setting the speaker as default audio output by following the steps below and check if it helps.

1. Right click on the sound icon on the right bottom corner of the taskbar.

2. Select "playback devices".

3. If "speaker" is not set as the default device, highlight it and click "set as default".

5. Save the changes.

Let us know the result.

 

problem with audio output devices (inbuilt speakers)

Hi Venka,

It happens that there's a corrupted file inside one of your system folders that makes the sound output inconsistent or not working at all. When a component of an operating system has been missing or corrupted, your computer will function in an unusual
behavior including its sound output systems.



Here's what you can do:

• There’s a built-in utility called System File Checker tool that helps users to perform scanning, repairing, and restoring of missing or corrupted files of a computer. You can visit this link:
  Use the System File Checker tool to repair missing or corrupted
  system files to know how to run this tool.
• Perform a full system scan by using Windows Defender.
• Update your operating system to the latest version.
• Test your speaker or any sound output by replacing them. Try the other device if it does the same.
• Update your audio driver by downloading it from the manufacturer’s website.

• There’s a tool that helps troubleshoot sound issues in Windows. You can visit this link:
