Changing default audio output to HDMI on Gnome 3

Pyrrhus · 06-04-2016, 11:03 AM

I currently running the latest Debian Testing on my X220 in Gnome 3. I haven't laptop connected to TV via HDMI using a display port adapter. Usually i just switch the audio output manually in Gnome 3 settings but I'm trying to use ZSNES on my TV. However every time I go into full screen mode it refreshes my TV to adjust the resolution which defaults the audio output back to my laptop speakers. Does anyone know how I can fix this problem? When I plug something in via the 3.5mm headphone jack it automatically switches the audio output to whatever is plugged in but this doesn't work with the HDMI cable.

You could create a file called .asoundrc in your home directory.

Code:

pcm.!default {
      type hw
      card 1
      device 7
 }

You'll have to change the values to what need for sound over HDMI. You'll probably also have to remove/rename the file and login again when you want sound on the internal speakers instead.

Hm this solution isn't ideal but I guess it'll have to do for now. Thanks for your help!
