This bug has been affecting me since upgrade to 13.04; 12.10 and 12.04 were fine. This is on a FiiO E10 USB DAC.
It's not just slightly crackling -- it's completely mangled audio! Slowed down about 30% and full of extra noise. I'm trying to work out if it's synchronous or not according to the lsusb output.. In there it says "Transfer type: Isochronous" and "Sync type: Adaptive" often. -- 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
