[alsa-devel] non-blocking mode example

[ThomasJF]

Thank you again Clemens,

now it is working with poll and the two fds. Also pause, play and stop.

If it stops, the snd_pcm_wait in my loop returns a negative error code 
and the state changes to SND_PCM_STATE_SETUP, then it finishes and 
everything seems to be ok.

Anything to do here?

Best regards
Thomas
