Today I updated the software on my Fedora 36 and now there is no
sound. I used Gnome Software to update. Neither VLC nor Firefox
produces sound. In Settings -> Sound -> Output there are two values
under Output Device, both saying HDMI/DisplayPort - Built-in Audio.
No difference between them, when using the Test functionality both
stay silent.
Any advice?
What updated? That might give a hint of what is causing the issue.
How many sound devices do you have? The two you mention sound like
they are from the video hardware. Is there another device built into
the MB?
Look at the output of lspci to see if all the sound devices are there.
Look at the output of aplay -l to see if alsa is aware of all your
devices.
If alsa knows about your device, does
aplay -D [device name] [some.wav]
produce sound output?
Check in the journal with
journalctl -b0
to see if there are errors during sound discovery.
Someone else had a similar problem recently on this list, and it was
suggested they try an older kernel. You could try that. Unforunately,
they never posted back about the resolution of their problem.
It might be that some of the updates you got need a reboot in order to
actually be instantiated, so just a reboot might fix the sound
discovery process.
