Hello. I still have this problem in Ubuntu 13.04. The sound fails all the time, and the only way to fix it is to manually change the sound controls in the sound panel. By changing balance and volume, it comes back. As soon as I increase or decrease the volume again, it goes bad again. The only way to prevent this is to only change volume in the hardware.
Please note: I don't have any problems when using stereo headphones. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/445849 Title: Highpitched rattling like sound with 5.1 surround configuration To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/445849/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
