The auto detection code for both alsa and portaudio has 192000 as the max sample rate - this could possibly be increased for alsa so you don't need the -r option. Could you test if this works (it means removing an if clause testing for 192000 in test_open). For portaudio I need to look at the library to see what limits it to 192k. ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=97046 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
