It was easy to fix this by adding the following line to /etc/pulse/default.pa load-module module-alsa-sink device=hw:0,0
After doing that and rebooting, I had to set the analog device as the fallback device in pavucontrol. (Before the default.pa change, the SPDIF device had been the only playback device there.) So, sound works now. But, why did I have to do that? Why was the SPDIF device automatically detected but not the audio device? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1872791 Title: PulseAudio doesn't see analog output on Dell Inspiron 6400 with STAC9200 Status in pulseaudio package in Ubuntu: New Bug description: PulseAudio currently doesn't see the analog audio output in my Dell Inspiron 6400 laptop with Intel HDA STAC9200 audio. It only sees the SPDIF output. This is the situation in both "pactl list sinks" and pavucontrol. I hear no sound from applications, probably because it's going to SPDIF. I don't have a way to listen to SPDIF to see if that is indeed the case. ALSA sees the analog output and "speaker-test -D plughw:0" plays sound through the laptop's speakers. This problem never happened in Ubuntu 19.10 and earlier. It might have worked earlier in 20.04 also, but I'm not sure of that. Rebooting didn't help. Purging and reinstalling pulseaudio and its automatically installed dependencies didn't help.
