I need more details on exactly what snd_pcm_wait() is supposed to do. The documentation on the www.alsa-project.org gives: - Wait for a PCM to become ready.
Parameters:
pcm PCM handle
timeout maximum time in milliseconds to waitReturns:
a positive value on success otherwise a negative error code (-EPIPE for the xrun and -ESTRPIPE for the suspended status, others for general errors)
Return values:
0 timeout occurred
1 PCM stream is ready for I/OSo, when is a PCM ready?
If a PCM is already in SND_PCM_STATE_RUNNING, when is snd_pcm_wait() supposed to return ?
I have discovered a problem with xine when using it. I have done a work around in xine so that dmix now works in xine. I think that my assumptions regarding snd_pcm_wait() might have been wrong, so I want to get accurate details from yourselves.
It also might be a good idea to update the documentation for snd_pcm_wait() with more details.
Cheers James
