I re-implemented the first solution and checked if the mode is indeed non-blocking. This solution assumes that the apps cannot go back to blocking mode at a later stage. Is it a valid asumption, or can the blocking mode be enabled/disabled at any time with snd_pcm_nonblock()? -Pierre _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
