1 PCM stream is ready for I/O So, 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 thin...
4) If snd_pcm_wait() is waiting, and with another thread we change the avail_min value, will the snd_pcm_wait() use the new value, or is the new value only used on the next call to snd_pcm_wait() I have discovered a problem with xine when using it. I have done a work arou...
