As you are no doubt aware there are significant infrastructural changes in -current relating to SMP scalability. It's in a very interim state at the moment, and one of the downsides is increased interrupt latency and lock contention for certain operations (yes, audio playback is one of them). Basically, it's a known issue. Kris
