had this issue on 12.04 but after some sec it went away on vlc by let it play the movie.
then on upgrade to 12.10 it became worse, it was always present and although after a while disappeared any jump back (shift + left arrow) made it come back. fixed it by removing rtkit and restarting pulse, my audio is: 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751265 Title: pulseaudio distorts VLC audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/751265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
