Gets interesting:

Just curious, this happens also with older BIAB versions? Realband works OK?

Related to a type or brand of internal software or hard ware audio routing and or Audio interface?

Is this laptop related? Type of interface? USB settings (USB hub power management off)

Processor type? MAC also?

Windows bloat ware or type related? Windows sounds set to off on in Control Panel? Power options set to NEVER?

Have you set all other audio routings to DISabled in Windows Device Manager. (uninstalling won't work !)
