Talk about a off the wall problem. It turns out the Bug was not with the Mac Studio or Sonoma 14.4. It was a bad HDMI port on my Yamaha AVR. I restarted the Mac and but the screen stayed blank, after the reboot. I ran an HDMI cable directly from the mac to the monitor and it monitor opened normally. I swapped out the HDMI cable between the Mac and the Yamaha no joy. so I tried an unused HDMI port and it works. A fast check and the Sound tab works normally.🤷♂️
