Surround Sound on Ubuntu 14.04 with Logitech G430?

Solution 1:

This site helped me out with that same question. I'm using the Logitech G930 headset. Edit the PulseAudio daemon.conf file by opening a terminal and enter:

gksu gedit /etc/pulse/daemon.conf

And search for: default-sample-channels. Remove ";" from the begining of the line, and instead of "= 2", change it to the number of speakers your system has. For instance if you have a 5.1 system, the number should be 6, for a 7.1 system: 8 and so on. This is how that line used to look before you made any changes:

; default-sample-channels = 2

And this is how it's supposed to look after:

default-sample-channels = 8

2. Now you can save the changes and either restart your computer or:

killall pulseaudio && pulseaudio

3. Check to see if the channels are muted. Open a terminal and type

alsamixer

4. You can now test the channels by typing this in a terminal:

speaker-test -c 8

Again, replace the number with your number of speakers.
