I wanted to check how many people had this problem, and if someone has found a fix.
If you press FN+(audio up) it doesn't work. The command connected to this combination is: amixer set Master 5+
this did not work for me so I changed it to amixer -q set Master 5+
. This worked untill I rebooted the system. Audio down amixer set Master 5-
works perfectly, so does mute.
Who is affected?
Any fix?
