I tried the suggestions from Murz, but this only fixes my subwoofer, the noisy highpitched sounds come again when i move the soundslider a little bit up and down.
my current workaround is using gnome-alsamixer to move every slider to 100% except the master slider, this slider can be used to increase or decrease the volume. when using the pulseaudio slider, the sliders in alsamixer got moved in some directions and produce bad sound. -- 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
