Musescore 4 doesn't play music - Soundblaste AE-7 / Windows 11

Hi,
I recently installed Musescore 4 but it doesn't play any music - Musescore 3 instead works flawlessly.
What seems odd in preferences -> in and output i cant set the buffer size of the device.

My System:

Windows 11

Soundblaster AE-7

Thanks for your Help!
