[Bug 1939205] Re: sound dummy output 21.04

According to the log of #8, the pulseaudio fails to detect/initialize the sound card:
0 card(s) available.
2 sink input(s) available.
index: 3
driver: <protocol-native.c>
flags:
state: RUNNING


Is the ubuntu you installed the stock ubuntu 21.04? From the log you provided, the kernel and audio driver worked well, but the pulseaudio had some problem.

Could you debug the pulseaudio to find why there is no valid sound card
in the PA?
