By using snd_pcm_avail_update() I found out that polling on the PCMs *does not work at all*. Although I verified that avail_min is 160 frames, polling on the capture/playback PCMs returns a POLLIN/POLLOUT event even if the number of frames for reading/writing *is less than avail_main*. I also tried snd_pcm_wait() which should also wait until there are at least avail_min frames available for reading/writing. The result is the same: snd_pcm_avail_update() shows that it returns even if there are far less than avail_min frames available for processing. I suspect that this is a bug in ALSA ? cheers, stefan _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
