windows 10 21H1 presonus Asio outputs not selectable


Posted (edited)

Since the windows 10 update to 21H1 I can no longer select Asio as a choice my presonus  24c outputs are listed but not selectable, the onboard realtak device is though. However as soon as ASIO is selected Cakewalk goes in to an unresponsive loop.

Presonus are having a look but they cannot see anything wrong with the installation of the 24c from the system log.

I installed using admin so the install is fine, select WASAPI as my driver of choice is absolutely fine, the Aud.ini has both the real tek and the presonus listed as Asio with the same parameters defined, but only the realtek can be selected, and of course the unresponsive looping makes Asio unusable, seems to be an issue when cakewalk is iterating  over the device and is only activating the first as selectable.

Any help with the cakewalk side of things appreciated, Presosnus are already checking this so not an audio interface issue so far.
