DIY Street Linux Thread. in OS: Microsoft Posted October 12, 2006 Has anyone got 5.1 audio working on linux? Yes, and believe it or not, out of the box on CentOS, my 5.1 USB audio headset in Doom3 native, actually gives me 5.1 of positional audio that is just plain SCAREY!!! That's from me, a 48 year old guy. Does it sound the same on my XP OS, no it does not. Apparently the USBAUDIO modules in linux are really built right. When I play a DVD with 5.1 through the ALC850 coax, I do get 5.1, but it was a real pain. Each application (about 4) has different setups to get that darn 5.1 working. Sometimes, it's /dev/dsp1, sometimes it's /dev/snd/put-archiac-sounding-device-name-here . Documentation for ALSA blows chunks. If you do get sound working out of the box, DON'T touch it, you will only break it beyond fixing, and nothing you will do, short of a reinstall, will fix it. I have over 12 years of linux experience, and sound has been a thorn in my side (along with trying to ATI video drivers to go 'accelerated'). If I were to reload this box, I would put Ubuntu on it. Very up to date, and very user friendly once you figure out how to do 'updates'.
