I dual booted ubuntu on macOS Big Sur
After installation everything works fine but, there is no sound
Pavucontrol shows that sound going out but i don't hear
I already maxed the volume in the alsamixer
systemctl --user status pulseaudio gives me: Active (Running)
And my sound card has been detected by system
I don't know how to fix it

Does the mac book have a hot key for sound? I am not familiar with MacBooks.

http://manpages.ubuntu.com/manpages/...er-test.1.html

Also . Pauvcontrol may be muted or alsa utilities may be muted. Wondering here if

Code:

alsamixer

Might have something muted or pauvcontrol has something muted. You can google how to unmute pauvcontrol in Ubuntu if the sound test works out for you.

I solved it by downloading drivers from github repo: https://github.com/davidjo/snd_hda_macbookpro
