I decided to finally install Ubuntu 8.04.1 on my desktop today. One issue I seem to always have with a new Linux distribution is trying to figure out how to get surround sound to work with my sound card. My desktop is currently using the Creative Audigy SE sound card (ca0106) which can be very un-Linux friendly.
With Arch and Gentoo Linux, I was able to get surround sound on all five speakers with the following .asoundrc file:
In Ubuntu, I was not getting surround sound with the above file. I decided to copy it to /etc/asound.conf to make the settings system wide. When I rebooted Ubuntu, I got surround sound when the login screen (gdm) popped up but once I logged in, only three speakers were working.
Then I found this post:
load-module module-alsa-sink device=”surround51″ channels=6 sink_name=sur51
It worked for me and should work for others as well. Now I have surround sound 🙂
