[Alsa-user] Message "ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM default1 prog_name: pcm_params.c:2286: snd_pcm_hw_refine: Assertion `pcm && params' failed."

[Xiaofeng Li <xl...@gm...>]

I programmed with a IPC protocol API with ALSA, and when I entered
devices name are malformed and my program crashed and returned the
following message in stderr. I think besides a non-nagative number
returned by snd_pcm_open, this breaks the protocol I am using. Can't
do too much on the other APIs.

ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM default1
prog_name: pcm_params.c:2286: snd_pcm_hw_refine: Assertion `pcm &&
params' failed.

Is this a bug? I have seen several people sending massive messages
that has this one.


Thanks.
