Having that problem too. MME or WAS is not an option for me as I need to get the audio channel 3 on my ASIO device to record audio, can't do that unless I can use ASIO. AND I can't record audio in 64-bit without extreme latency with my ASIO driver. This latency was a problem in BiaB 2020 that I was never able to fix -- I tried everything tech support suggested to no avail. So I stayed with the 32-bit version of 2020 and everything worked fine. But now I can't do anything with 2021 as far as recording audio goes. Really disappointed at this point, I'm going to have to re-install 2020 to get anything done in the meantime. Good thing we get discounts on the early releases -- I guess this free beta testing is why...
