Here's the story - I have a Waveterminal 192L that has 8 physical outputs (6 analog, 2 digital) Since I do all my GS3 work in stereo, I only enabled channels 1 and 2 in the GS3 setup window. BSOD on any kind of capture. Just for yuks I enabled the other channels in GS3 and now no BSOD. Unfortunately capture is still hosed. The recorded file only has audio on one channel with dropouts and nasty distortion. At least I can play with other settings now to see if this can be corrected without having to restart my machine each time.
