snd_pcm_prepare() is required to recover the stream from XRUN or any other errors. But, for the recovery purpose, we have now snd_pcm_recover() as a generic solution, too.
It appears that (currently) the additional benefit of snd_pcm_recover is simply that of resuming the stream. However, I haven't seen any details on when/why a stream would become suspened and require this type of recovery.
Also, in SALSA, it appears that snd_pcm_recover can -block- even if the stream has been configured for non-blocking behavior.
