Thanks Bob.

Well that probably explains it - except that in Mixcraft I have 3 driver options Wave, ASIO and Wave RT. And I have Wave ticked - so shouldnt be using ASIO. The ASIO control panel doesnt open up, so it shouldnt be using it.

Even more strange if I open Mixcraft and do select ASIO, I get no sound even without BiaB running.

I can switch Biab backk to MME(WDM) - but then I'm stuck with my latency problem that i started this thread with.

The workaround for me I guess is leave BiaB with ASIO when recording, then if I need to open Mixcraft at the smae time, switch Biab to WDM. Bit of a pain though.
