First, those are not warning messages; they are debugging messages. Therefore they should not be stored in your system log or printed out.
Second, if you are using a USB webcam then the webcam can't send audio data to the system if no processing is asking for it. Third, the messages indicate that the audio I/O was blocked for more than 0.25 second. That's a very long time for this sort of thing. You might try to find out what caused that blockage and fix it. -- 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
