Sometime this November 2021 my audio stopped working but only in Windows 10.

When I boot to Dell Diagnostics it passes the audio test and audio can be heard coming from speakers.

When I boot to WinPE 10-8 Sergei Strelec I also hear audio coming from speakers.

The device manager in Windows 10 shows the devices as working normally however the speaker icon near the notification area has a red X on it and hovering the mouse over it shows "No Audio Output Device is installed."

I have uninstalled and reinstalled drivers and did an in place reinstall of Windows 10 21H2. The problem occurred on 21H1.

It's happening on a Dell Inspiron 3541.
