sorry, i haven't changed the code yet since i have no time left for
investigating this problem.

can you do the following small test?

- playback a 44100 (or 48000) hz file
- suspend/resume
- playback the same file again.
- if the playback is too fast, playback a file with different sample
  rate once.
- playback the file above again.


also, please get the dump of /proc/asound/card0/ac97#0regs
before and after suspend/resume (and after playback, too), and compare
whether the values are different.


thanks,

Takashi
