Sorry for adding so many comments. I always find something else to try out.
The default setting in pavucontrol (that I get after deleting ~/.pulse) is 71% for the left/right front/back satellites, 63% for front and subwoofer. When unlocking the separate channels, driving one up to 100% (& getting noise) and resetting it back to the original 71%, the noise is still there. -- 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
