Ubuntu – Surround Sound on Ubuntu 14.04 with Logitech G430


I have a Logitech G430 headset, that comes with 7.1 surround sound.
On Windows 7, I have the Logitech Gaming Software installed, which allows me to have surround sound on my headset.
I was wondering whether there was a Ubuntu method to allow me to get surround sound on my headset, becuase the methods I have tried haven't worked =(

Any tips?

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

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

killall pulseaudio && pulseaudio

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



  1. 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.
