I've seen changing the buffersize resulting in crashes too. For the rest
it appears stable to me.

I didn't know about this patch. Nice. I get 37ms at 44.1kHz and 28.6ms at
96kHz. I also use 256 sample buffers.
I just "discovered" that the "-audiobuf" flag is used in ASIO too. I
wrongly assumed it was only there for MME.

I was assuming that only the HDSP buffer was there.

Thanks for pointing me to this patch.
