The new Ubuntu 8.04 look very good and has many improvements over the older releases. I will not discuss about them now. I’ll just stick on the new default sound server, PulseAudio that offers sophisticated mixing capabilities and network transparency.
The purpose of this post is to help other Ubuntu users to enable 5.1 surround sound on their computers, using PulseAudio (you must have a 5.1 capable sound card).
I have a Creative Labs SB Audigy sound card but I tested this solution on a Creative Labs SB Live!. The results were the same in both cases.
The solution is very simple. Run this in your terminal:
sudo joe /etc/pulse/daemon.conf
Uncomment the line containing:
default-sample-channels = 2and replace '2' with '6' (if you have a 7.1 card, replace '2' with '8')
Restart the window manager and enjoy the new sound!

Run ‘speaker-test -Dplug:surround51 -c6 -l1 -twav’ in your command line. That way you’ll not if you have 5.1 sound.
