It’s been a while since I bothered, the reason being it’s always seemed like an un-worthwhile struggle to get it working but either things changed or I was doing something to overcomplicate the process but it’s actually pretty simple to get surround sound up and running on your Linux machine. Now, I’m not going to go in to how to install the drivers for your specific sound card, because there are so many and I don’t have them all and most times on most popular distributions (Debian, Ubuntu, Mint, Fedora, OpenSuse etc) you’re going to notice that the sound card is actually already supported. What I will be doing is showing you how easy it was to get my 5.1′s set up (and the same will be said for 7.1′s).

Step 1:

First off you’re going to want to edit the pulseaudio configuration file to add the number of speakers you’re using, it’s default is set to 2.

Near the bottom of the file, there will be a line which looks like this:

;default-sample-channels = 2

The semi-colon is a comment, so this line isn’t actually doing anything unless you remove that. I would suggest leaving that line alone and adding a new line at the bottom:

default-sample-channels = 6

If you’re using 5.1′s the number of channels will be 6, 7.1′s will be 8 and I think you get where I’m going with this? So in this example, I’m using 5.1′s.

Now save and close that file. You’ll need to reboot your system now too, so that these changes will take effect.

Step 2:

So you’re back? Good..

Now you’re going to want to open up the Sound Preferences, usually you can do this by clicking on the little sound icon in your panel, or System > Preference > Sounds from the menu.

From here, you’ll want to click on the Hardware tab. Near the bottom it’ll say Profile: with a drop down box next to it. Here you can select the type of set up you have, as you can see in the screenshot I have an “Analogue Surround 5.1 Output”, yours might be different and that’s cool and if you don’t know feel free to try a few out. Next to that drop down box is a button which says “Test Speakers”, this didn’t work for me so I have to use an online test but give it a try as it might work!

That’s it, you should be done!
