Public bug reported: Sound is not working, even after it did for a while seemingly because of elevated user privilege for audio devices. (someone came up with the recommendation.
I really do not understand why it regressed again. Symptoms: Hardware section in standard Sound Preferences is not populated again. As one can see from the attachments, cat /proc/asound/modules delivers 0 snd_hda_intel and lsmod | grep intel delivers snd_hda_intel, snd_hda_codec, snd, which looks good to me. pulseaudio is 1:0.9.19-0ubuntu4. What does the colon has to do there? This bug is very annoying.
