I had the same problem after upgrading to 21.10, what worked for me was:

1. to remove pulseaudio and alsa (sudo dpkg --purge --force-depends pulseaudio alsa-base alsa-utils);
2. to install pipewire-pulse (sudo apt install pipewire-pulse) and
3. reboot

Installing the pipewire-pulse package solved it on Ubuntu 21.10 impish:

sudo apt install pipewire-pulse -y
