Hmm, the stacatto could be caused by debug printks - the slow default speed of the serial port in DC mode can slow the entire kernel. I thought I had turned these off, I'll check.

The pops...ok, I'll have to do a ramp up/down thing. I hope your tweeters aren't damaged.

Go back to something speaker-safe for the moment. I've got some code changes to make, probably late tonight, or tomorrow.

Thanks.
