Not sure if I'm right here but I have a very hardware specific question. Just installed Kubuntu 13.10 on my gaming rig yesterday (to play KSP on 64bit ;) ). And so far everything worked rather well (not a linux pro here).
However I've been having trouble with my sound. As I mentioned in the title I'm using the Sabertooth 990fx audio controller with a normal set of 2.1 speakers. In addition to that I have a front panel connected to the motherboard where I plug in my 3,5mm analoge headset.
In the system settings it displays me all sorts of audio output options, including some 5.1 and 7.1 (that shouldn't exist) but none of them in no configuration outputs anything on the speakers connected to the back.
In addition I can't find any sound drivers in the list of "additional drivers" that it sugests me to install (only two ATI graphics drivers).
Hope someone can help me with this. ASUS doesn't seem to have official linux drivers :C
