alsa-sink.c: ALSA woke us up to write new data to the device, but
there was actually nothing to write.
Sep 03 14:33:23 username pulseaudio[1081]: E: [alsa-sink-USB Audio]
alsa-sink.c: Most likely this is a bug in the ALSA driver
'snd_usb_audio'. Please report this issue to the ALSA developers.
Sep 03 14:33:23 username pulseaudio[1081]: E: [alsa-sink-USB Audio]
alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent
snd_pcm_avail() returned 0 or another value < min_avail.

During this time period, I do believe I was starting an android
emulator and also watching a twitter video that had audio.
