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. Quote: "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. -- Highpitched Rattling like Sound with 5.1 Surround Configuration on Karmic Koala https://bugs.launchpad.net/bugs/445849 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
