First, what version of BIAB are we talking about? I am now suspecting it is OLD. And no you do not need ASIO driver for audio output. I use MME and select my MOTU Main Out 1-2 with no issues (I don't see any other selection choice for the MOTU in this case).

Windows updates, ya that could mess with sound. BIAB can be picky with ASIO so maybe you need to reinstall your MOTU Asio?? I find reinstalling the MOTU drivers has fixed problems in the past.

Or, Can you upload the file and we can test to see if it is a file corruption issue?
