The engineering team is aware of the looping and no sound issue that some users are experiencing in MacOS 10.14.6 and 10.15.6. We are hoping to resolve the problem in an upcoming update.
Have you tried the kext/unload, kext/load solution described above?
Another option is to rollback your installation of DPS for Mac to version 188.8.131.52.
First, please uninstall DPS using the uninstaller program found in your Applications -> Bongiovi DPS folder then restart your machine. Then please install the older version and let me know the result. Please feel free to email me directly at firstname.lastname@example.org
