Asus Speaker

I recently purchased an Asus ZenBook 3 to replace my aging Thinkpad X220. Most things work right out of the box just fine, but I noticed the audio function controls having no affect on the actual volume of the laptop.

Volume Controls

After a bit of Googling, I came upon an old Ubuntu Forums post with a solution to my problem. Credit goes to a user named hanni_ali.

Taking Back Controls

First, we find and edit the PulseAudio config file for analog output:

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

Then, we locate the following configuration entry:

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

And replace it with:

[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

Finally, we save the file and reboot the laptop. When things are all started up, the volume controls should work!
