With 1.0.17rc3 snd_pcm_rewind() is broken for softvol as it seems:

- Sometimes the sound becomes heavily distorted after such a seek:


- And snd_pcm_rewind() might return a value that is higher than was
  passed in, which as far as I understood should never happen:


These two issues might be caused by the same error.

Takashi, Jaroslav, how can I bribe you into fixing this? I'd love to
release my new PulseAudio version soon which heavily relies on
snd_pcm_rewind(), but unfortunately the most important driver (hda
with softvol) makes the most problems with it. :-(
