Very likely that the sound device drivers somehow got lightly corrupted. This can happen when a program like BIAB freezes, or otherwise does not exit in proper fashion, leaving a bit or byte out of place, etc. I have seen this before.


Sometimes switching drivers like that can cause the program to readdress the soundcard driver properly, as has happened here.

Other times, it may be necessary to re-install the sound driver software.

There is a command inside BIAB that may also do the trick when things like this happen. Under the OPTIONS menu, select "Return to Factory Settings" and select button number 2, which not only resets all the user settings in BIAB, but also reinvokes the Sound and MIDI setup wizard as if you were just installing the program.

Something to keep in mind for the future,
