Ubuntu 20.04.1 LTS, locks automatically. And after this sound output switches to dummy output. The sound setting gets normalized after restart only. And all the processes taking place terminates. Help me with this. Due to this issue video call gets disconnected in between only.
lspci -v | grep -A7 -i "audio"
and then see this recent answer askubuntu.com/questions/1218413/output-device-is-dummy-output and/or askubuntu.com/questions/1266611/…pulseaudio -k
. Does this restore the sound?journalctl -p warning | grep pulseaudio
when this happens?
