Progress rapport:

I have changed the driver in Baib from ASIO to WAS. I now have sound! I have double checked with several songs both MGU and SGU, of these one particular song (and unfortunately the song was newly downloaded thus the one where I first discovered the sound issue) seems to be a bit wonky in that it will sometimes play one time only, or not at all. The ASIO drive seems not work with the Volt AI, though ASIO did work with my previous Behringer AI with no problem. This pleasure of having sound is now so new that I have not had the opportunity or time to discern whether the WAS drive affects the sound quality on Biab or not. While this puzzles me, it works and I see no present cause for further endeavor.

I would now like to thank you all for various reflexions, ideas, analytical suggestions (especially based on my somewhat sketchy problem description), and of course support!

Thank you all!

Best regards and Happy Easter!
