Victor,

That's good news, glad to hear.

I thought itimer used the rtc behind the scenes but maybe we need to try
latching into the rtc directly for our timing. It's insane to have to
tweak.

Can you tell me if the sources you tested used the new usleep value? I
committed a change to use 1000 in that first usleep call but you may not
have updated and gotten it.

sound is still smooth. That's how it was tested in first place which is
close to 30 MIPS I guess...
