I have the same problem, Soundblaster live 5.1 Using 5.1 analog outputs.

I've done a bit of experimentation to see if I would be able to narrow down or fix the issue.

As suggested in the thread http://ubuntuforums.org/showthread.php?t=1276999 i changed the following.

"Check in /etc/pulse/daemon.conf and try uncommenting the line
enable-remixing=yes

You can also try changing the default sample rate from 44100 to 48000, some cards are only capable of 48000.

You can also try changing the default-fragments and increasing the default-fragment-size but that is usally necessary only if the sound is suttering.

You can read about these settings by typing in a terminal"

I also removed Pulseaudio the sound quality seemed to improve greatly, but only 2.0. I also attempted to build the latest Pulseaudio from source, but ran into dependency problems and have since abandoned the attempt.
