I changed motherboard on my computer, I now have one with Z68 chipset, and my problems with audio have returned. lspci gives this output: 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
If I set any audio setup that includes subwoofer (4.1, 5.1) as soon as I touch volume setting (with keyboard or mouse, any way), the sound becomes very distorted (see ogg recording I made). To make the matter worse, I installed 12.04 beta 2 and I have the exact same problem with audio. The recording I made is from 12.04. Changing PCM level doesn't help anymore. ** Attachment added: "How crackling now sounds" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/796262/+attachment/2975204/+files/Record000.ogg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/796262 Title: Sound on 5.1 system distorted after changing the volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/796262/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
