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?
