On the 1/1/2013, there was a post over on the Pi forum form jamesh, (who is also a Broadcom employee), talking about the Pi's USB implementation. (ie. the Synopsys IP included on the Broadcom SoC.) jamessh wrote: > Yes, the Synopsis design is a bit pants. Broadcom didn't know that at > the time.

On the basis that he is one of the few people that are privy to the IP and any documentation, (by virtue of being a Broadcom employee), and he describes it as being a "bit pants", I wont be holding my breath that we'll ever hear "perfect" audio from a UAC2 device driven from a Pi. Others, can come to their own conclusions. But I personally, wouldn't base any audio project where the requirement is for a decent USB out with which to use an external DAC, on the Pi. ------------------------------------------------------------------------ JackOfAll's Profile: http://forums.slimdevices.com/member.php?userid=3069 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
