I have witnessed similar issue. Basically, the sound starts crackling. Restarting pulseaudio does not help. If i either pause or let the crackling continue for several minutes, the sound starts properly working again on itself.
Unplugging and replugging USB cord also works (I have USB sound) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775076 Title: banshee sound crackle -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
