I am experiencing a similar bug since upgrading to 12.04 on a Dell Inspiron 9400 but only when using my external USB NuForce Icon DAC. The internal sound card
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) works fine (at least I can't hear any crackling there). I can provide further information if needed. The DAC used to work just fine on 11.04. Since I am using this laptop as a media center and to play music I would have to go back to 11.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/597035 Title: CPU usage dependent crackling on USB and internal sound card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/597035/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
