I just noticed an issue. I can't control the volume for DP (Icons are faded). See attached screenshot.

Could that really be reason it changed?

Nothing to do with audio.

Got it..."macOS does not provide HDMI/DP audio controls. No volume, no mute, no balance, etc. Use the connected DP/HDMI device (TV, receiver, etc.).

Well, it looks a I've all that is possible to work in place. Toleda, I truly appreciate your help! Thanks man!

I just would like to share that I learned about SoundFlower + SoundflowerBed to control volume on HDMI or DisplayPort Audio. It's working great for me on 10.12.6.

Good tip! Corrected.

Pascal/HDMI audio with the HDMI port does not work (hot plug does work).
Attach IOReg with DP display connected.

Attach IOReg with DP display connected.

DP connected is the one I use and sent.

(I used HDMI during install only - I believe, per instructions)
