The two traces are very similar. They show that both the audio-out and audio-in channels used latencies of 8 ms, which should have been absolutely fine. The only reasons I can think of for a problem to occur would be a bug in the OHCI hardware (which is not unheard of) or something disabling interrupts for more than 8 ms (which seems unlikely).
A usbmon trace showing the problem would help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1191603 Title: raring-updates: regression: 3.8.0-24.35 causes sporadic failure of USB audio devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191603/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
