Ah- found the writeup on Macs and why. Perhaps it will help with an idea. The Click problem seems to be really prevalent these days. -Paul -You probably have a Mac whose model has been introduced before 2008 end. These models have a limitation in their USB ports power supply that makes a few samples to be set to 0 every ~16,000, and this only in Integer Mode. And this is what you can hear as clicks. To continue to get the benefits of the Integer Mode, the most widely used workaround consists in connecting a powered USB hub between the DAC and the Mac. (With only the DAC connected to it of course).- -- paul.raulerson ------------------------------------------------------------------------ paul.raulerson's Profile: http://forums.slimdevices.com/member.php?userid=50346 View this thread: http://forums.slimdevices.com/showthread.php?t=82110 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
