My Windows 10 Pro, Fall Edition, (using the USB connection) states: "MONOLITH DESKTOP HPA Driver is unavailable"
Just installed the posted XMOS.dll and the error is gone. What I didn't think to do was try the USB connection before installing the XMOS driver. With the driver, the playback is fuller and louder than my other setup (Win 7, with TOS Link). I'd be curious to know if anyone notices a difference with and without the driver.
Now if my balanced cable would show up, I can really start my testing.
Interesting. You shouldn't need to use drivers on Windows 10 (post creator's edition) since it has it incorporated into the OS already. The only thing missing from the Win10 default package is the DFU Loader for firmware upgrades, but seems like you don't need it with the app that Monoprice provided.
