This is a long-standing bug with the maestro2 driver.
My current theory is that its a race condition where the APUs get confused while we update their control memory, but this doesn't make total sense. Some of the bug reports I get are implying that the sound is breaking when we're not touching the apu's control mem. Maybe implying a nastier silicon bug..
I've been meaning to try implementing a work around to the theoretical bug, but I've always had trouble triggering it :/
The fun part of this (and why you would see the bug in win2k) is that the maestro2 is very poorly documented. I've never heard of anyone having full docs on the APUs, including the people I've talked to at ESS. They bought the part from another company.. (and thankfully axed it in the maestro3)
so we're stabbing in the dark.
