With spdif out I was using a period count of 4. Setting the buffer time to 999999999 gave period and buffer sizes of 1024/4096 for all sample rates. With lower buffer time the buffer size and period size would be smaller. The exact buffer cut off that allows this behaviour is somewhere between 100000 and 999999999. cheers ------------------------------------------------------------------------ SBGK's Profile: http://forums.slimdevices.com/member.php?userid=52003 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
