 Replying to [ticket:839 mcarans]:
 >  Is the sink being wrongly unloaded? Or is it correctly unloaded on
 Rhythmbox exit but wrong that it is not then reloaded afterwards?

 From pulseaudiooutput_rateconverter.txt:

 {{{
 D: alsa-sink.c: Requested to rewind 55296 bytes.
 D: alsa-sink.c: Limited to 55248 bytes.
 D: alsa-sink.c: before: 4604
 E: alsa-sink.c: snd_pcm_rewind() failed: Unknown error 4604
 D: alsa-sink.c: process_rewind: Unknown error 4604
 E: alsa-sink.c: process_rewind: Unknown error 4604
 }}}

 That error causes the alsa sink to quit. To be clear, the first error (E:
 alsa-sink.c: snd_pcm_rewind() failed: Unknown error 4604) is printed after
 calling snd_pcm_rewind unsuccessfully. After that pulseaudio calls
 try_recover, which repeats the error message in the beginning of the
 function, so the second error is really from the same call. The third
 error message is printed after trying to call snd_pcm_recover() inside
 try_recover. It is only when that snd_pcm_recover() call fails that the
 alsa sink gives up and quits - if snd_pcm_rewind() would fail, but
 snd_pcm_recover() would succeed, the sink would keep on going.

 The bug is probably in the rate converter alsa plugin. I guess I can
 resolve this as "elsewhere".
