So as of this morning, the builtin microphone and speaker, along with headset speaker and microphone have stopped working on my Ubuntu 20.04. I have an asus zenbook. I have a dualboot installation (Ubuntu and Windows), microphone and speaker work perfectly fine on windows, so I assume that the hardware is fine.

On Ubuntu, I connected a display with speaker to the laptop through HDMI and the sound is played fine on the display. Laptop's builtin speaker still doesn't work. I've tried deleting and purging alsa and pulseaudio and reinstalling them, several times , but nothing changed.

I checked alsa mixer and everything seems fine:

As it turns out, windows sometimes sets flags on sound devices. I had recently used windows, so some sort of flag was set and ubuntu couldn't work with the sound system anymore. I logged back into windows, removed and reinstalled sound drivers and the problem went away!
