Graham, have you checked your audio in the device manager. I have a Roland Octa-Capture and if it isn't on during the Window's update Ms turns on my on-board RealTek audio. That can screw up audio. I have to go in and turn them off.

As soon as Win 10 starts to update turn on your printer and external audio interface. This way Win 10 knows what you have. As you know MS wants it done their way and if these aren't turned on Win 10 will set things up for you, regardless if you want them to or not.


I want my last spoken words to be "I hid a million dollars under the........................"

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
