[PATCH] Recover stream when it's suspended upon rewind

[lkundrak]

Error from snd_pcm_rewind() might mean we just woke up from suspend and didn't have a chance to try to recover the stream since we didn't write to it in between. Call try_recover() in such cases.

Note that for this to work kernel must return ESTRPIPE instead of EBADF for rewind/forward attempts on suspended streams, so that snd_pcm_recover() can recognize it should snd_pcm_resume() the stream. This is not the case yet (2.6.31-rc5), patch is available.

Recover stream when it's suspended upon rewind

This is the kernel part - just for illustration, it has already been submitted to lkml & alsa-devel, just seems to be pending in greylist now

Merged the PA patch. However I assume the check in try_recover() should actually compare with ESTRPIPE and not EBADFD, right? Otherwise the kernel patch would not match up with this PA patch, or am I blind?

[lennart]

OK, fixed the EBADFD/ESTRPIPE mixup now in git.

Thanks for the patch!
