I’m using a ROG Delta S Wireless headset, after installation of Fedora, I immediately noticed that I have no sound.
I played around with
alsamixer and found that adjusting “PCM” volume of my headphone works.
This should be the real volume slider.
I found the following relation between the Master volume and the PCM volume of my headphone:
- When PCM is 0 (no sound for me), Master is only 94 (whenever my system volume slider is below 94, I have no sound at all)
- When PCM is 50 (comfortable volume), Master is 97
- When PCM is 100 (too loud!), Master is also 100
So it seems that the real volume of my headphone 0%-100% is mapped to 94%-100% of system volume slider.

My other devices like HDMI output and 3.5mm output is working fine.
Is there any fix to this issue?
