[Bug 579117] Re: Wireless blocks USB-Audio, leading to dropouts

[Chris Hermansen]

Well, renice-ing rhythmbox down to -9 did not seem to help.  I got
stuttering every two-three minutes.  Besides the ath5k noise floor
calibration message, the only message I received during the test was

Jul  4 15:37:15 temuko pulseaudio[1273]: ratelimit.c: 848 events
suppressed

I don't always get the alsa-sink.c: Underrun! message, but I don't ever
recall getting the protocol-native message.

This group of messages which is occasionally but not always reported by
pulseaudio also puzzles me:

alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers.
alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

I have to say I'm pretty stuck at this point.
