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?
