JWise – What is your support ticket number? Is it an open ticket?
We are aware of some issues arising with DPS in MacOS 10.15.6. Specifically I have seen a few reports of crash issues when connecting a new Bluetooth device, as well as a few reports of audio looping in youtube and Apple music. Please feel free to reach out to me directly at firstname.lastname@example.org and we can try to find a resolution to your DPS-related audio problem.
In the ““The selected device has no sound outputs” issue, I would start by uninstalling/restarting/reinstalling. Make sure that the DPS Kext has been Allowed in System Preferences -> Security and Provacy -> General Tab. Then, verifying that DPS has microphone permission in System Preferences -> Security and Provacy -> Privacy Tab.
