Since there are a lot of Foobar users among us, in case any of you didn't know, Peter just released his WASAPI v3.0 drivers, with both event and push-mode playback.

I highly recommend downloading these drivers. They took care of an annoying bug I had with my USB/SPDIF converter's visualization, dramatically cut down on clipping when having a lot going on at the computer at once. I can't promise they'll wash your dog or sound any different, but I'm very happy with the new drivers.
