Sounds cool so far. Looking forward to it.

If you think it'd be helpful, I can try to apply the audio overlay patch to a Hijack v300 kernel. I gave it a quick shot last night but the patch was rejected, so it's going to take some time to manually figure out why it didn't take and hammer it in there... But it should be doable.

I can also hack up a version of pcmplay that will take advantage of the audio overlay. That's a much quicker fix.

Hopefully when Mark Lord comes back we can get him to include the audio overlay support as part of Hijack.
