the hardware of audio interfaces doesn't activate all by itself - it needs to be told to start processing i/o and generating interrupts. when you open a handle on either the playback or capture stream, ALSA doesn't start the hardware running. it only does that when you tell it to, with snd_pcm_start(). without this design, there would be no way to stop and restart the hardware without closing/reopening the card, which is a silly model to be using. --p _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
