Coolstar Audio Switcher not switching. (CN65 Win11)

System:
Asus Chromebox 3 (CN65/Teemo), i7-8550U, Windows 11
Latest @MrChromebox firmware.
Audio SST drivers from Coolstar
All other drivers up to date as per Snappy Driver Installer Origin

I have audio over HDMI, USB-C and Aux Port all working thanks to the SST audio drivers from @coolstar and Snappy Driver Installer Origin, however the audio is not switched automatically on insertion/removal of a 3.5mm jack from the aux port. I need to manually change the audio output device every time from windows settings.

The audio switcher app is installed by Coolstar installer and the service is running as expected but I do not get the expected swapping of audio output devices.

I emailed the Coolstar support email ([email protected]) but have not had a reply.

Any advice of fixing this? Any further information I can provide to aid debugging?

Thanks
