cool I tried DPC on my XP partition, and it only spiked when I had the wireless enabled, but I have no way of checking on the OSX side, but I can assume it would probably do the same thing. Also, I send everything through my analog mixer so I can monitor that way, and then have all the signals piped through into the 828. I'm just wondering, aside from the wireless thing, what impact not having set any request sample rate/buffer sizes would have had on recording.
