Hi joden,
I don't visit this thread very often and, today when I did, I noticed that in an earlier post you said,
I am getting tired of having to keep re-setting the audio interface back to 48 after using BIAB.
I have my soundcard set to 48 kHz and never have to reset it. It changes between 48 kHz and 44.1 kHz automatically.
My operating system is Vista and what I did, a few years ago, was to go to "Control Panel", select "Sound", then "Playback" (1). From there I double-clicked on "Speakers" (2), selected the "Advanced" tab (3) and then activated the "Applications take exclusive control" (4) option.

This works for me. Maybe set-ups have changed in Windows 7 but I mention this on the off-chance that it's useful information.
Best regards,
Noel.
