Maybe an error in snd_pcm_drain - not sure what effect it might have...
snd_pcm_group_for_each_entry(s, substream) {
runtime = s->runtime;
...
}
up_read(&snd_pcm_link_rwsem);
snd_pcm_stream_lock_irq(substream);
/* pcm_native.c around line 1491: */
/* error? runtime has been changed by group_for_each
should use substream->runtime instead?
*/
/* resume pause */
if (runtime->status->state == SNDRV_PCM_STATE_PAUSED)
snd_pcm_pause(substream, 0);
