Sometimes the stream may be stopped due to XRUN events, in which case the userspace can call snd_pcm_drop() and snd_pcm_prepare() to stop and start the stream again.
In these cases, we must wait for the DMA channel to synchronize before marking the stream as prepared for playback, as the DMA channel gets stopped by snd_pcm_drop() without any synchronization.
We should really implement the sync_stop() PCM callback and let the ALSA core let care of the sync.
Good point, that's a better idea.
Thanks for the suggestion, sending a v3 with the change.
Peter, I've kept your R-by intact as it is a minor change.
