Did this bug not happen with the 3.8.0-rc6 kernel? If that is the case, I can perform a bisect to identify the commit that introduced this regression.
Also, the v3.9-rc3 kernel is now available. Can you also test that kernel, to see if this is already fixed in mainline? http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc3-raring/ Thanks in advance! ** Tags added: kernel-da-key -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1136110 Title: USB Audio Codec choppy playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
