Hello,
I just installed fedora 37 on an iMac 27 18,3. Everything is fine except there is no sound.
settings/sound/
- the selected output device is
Dummy output
and there is no other choice. - there is no input.

From the search results, I see this a known issue.
Most topics don’t provide a solution (ie on ask fedora /t/intel-audio-issues/19370/32).
This topic seems to be similar, but it points to this kernel module which I don’t know how to use.
Also, I tried
sudo nano /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=auto,imac27
But it does not work.
Do you know how to make the audio input and output work on an iMac 27 on linux?
Thank you
