Just did a fresh install of Ubuntu 22.10 on my Asus Zenbook 14 OLED (model Q409ZA) but I have no audio. I followed a guide on installing pipewire, but that did not work. I saw some other questions that were related as well but didn't find any solutions. I do see in the settings that the bar is moving when I have audio playing. When I try to do the test audio, nothing is played there either. Attached is a screenshot of the PulseAudio Volume Control output devices. In windows the device is listed as Realtek, so I don't know if there is some kind of driver issue.
Edit:
I did have to reinstall Ubuntu but after the reinstall I did have the same thing - no audio. Followed another guide Fix No Sound Issue but the only thing I found a bit weird was my output of pacmd list-sink-inputs was 0 sink input(s) available. even though I had audio going through VLC and Firefox. I tried doing what one of the answers said, which was to do the inxi -xxz --audio which showed that pulseaudio was not running. So I did the commands systemctl --user enable pulseaudio and systemctl --user start pulseaudio which then failed, so I restarted, then started pulseaudio, which did start, but still got no audio, checking the status of pulseaudio again I got the following:
