Volume control on asus zenbook 3

Using Ubuntu 16 LTS

I installed ubuntu on my new asus zenbook3 ux390. Nearly everything works fine except the volume controls don't work. The volume is either on or off. I can adjust volume in specific apps or websites (like youtube) successfully, but the internal volume control either wants to be muted or at 100%.

Solution 1:

Your problem may be related to Ubuntu not detecting all your speakers correctly. I solved all sound related problems on my Zenbook (UX390UA) by editing:

sudo nano /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common

and changing this section:

[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right

Into this:

[Element Master]
switch = mute
volume = ignore


[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right


[Element LFE]
switch = mute
volume = ignore

save (with Ctrl+x) and restart pulse audio:

pulseaudio -k
