Jwise – What is your support ticket number?
If you are seeing the “No sound after updating” issue, please try this solution:
1.) Quit DPS
2.) Open Terminal and run the following commands:
sudo kextunload /Library/Extensions/DPSReflector.kext/
sudo kextload /Library/Extensions/DPSReflector.kext/
Note: You may need to do the first command twice (might fail the first time).
Please let me know the result of this.
