Be advised that BIAB can only address ONE audio device at a time.

If you intend to also have an output to a PA system in live performance, such as the Line Out or Analog Headphone Out as Line on a laptop, selecting the USB Audio Device to be headphone would likely turn the other output OFF.

Rather than a USB headphone set for live use, I'd go with using a headphone output from the PA amp/mixer, so that all was derived from the same audio stream.

This would also eliminate any change of different throughput times (PA system ahead of or behind the headphone output) -- even if you did manage to kludge dual outputs from BIAB.
