Windows 10: Need help for audio output device on my Lenovo

Need help for audio output device on my Lenovo

:)

 

no audio output device installed

I've tried every step that was suggested, still getting no audio output device installed.

 

No audio output device

As regards your Lenovo log, I came across this:

[QUOTENotes:

Lenovo System Update was previously named ThinkVantage System Update (TVSU), and is one of the ThinkVantage Technologies

• Lenovo Vantage includes Lenovo System Update

Are you confident you have the latest Lenovo System Update? (It's possible the software hasn't been recoded to match, I suppose, so internally still refers to TVSU). Plenty of similar reports on their forums, random example:
Lenovo System Update 5.07 failes to download packages - Lenovo Community

- so that's somewhere you could ask further about that.

There's a basic failure to make contact logged.

You could try an in-place upgrade repair install which keeps all progs and data - you'll need a 1909 iso file - use the MS media creation tool.

That will reset services to default, provide a new set of drivers etc.

** Note this very similar situation: search for Panocek's post, and alex5723 's suggestion at the end:

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?
