You need to set Studio one output to windows device, not your usb interface. Then create an output from your usb interface to the input line in for windows. So that everything is being played through windows devices. Does create a bit of lag on your mic, but not too bad.
I just used the inbuilt windows game bar (Alt+G).
In the setting for the gamebar, set it to record all audio (not just game and mic which it defaults to).
Then to set up your gear:
Connect "headphone out" from audioboxusb (or your usb interface) to line in on laptop (dont know if you can use mic input if you dont have line in. Probably, but will need to turn down gain on mic in windows volume settings i suspect).
Connect your headphones to headphone out on laptop.
In Studio one, set output to "windows audio" in sound setup instead of your usb interface.
In windows sound settings – Set output and input to default windows devices. Realtek in my case.
Note, my mic is still connected to my USB interface. I would imagine you can connect a usb mic to the laptop though.
I also set studio one to be identified as a game in the gamebar – don’t know if that’s needed though.
S the key is setting Studio one output to windows audio and then making a loop.
