sound not working on studio display
Mac Studio computer with two Studio Display monitors, macOS 12.5. Sound is not working on either of the Studio Displays for any type of sound - music played through QuickTime, any sound through web browser, etc. Sound works for about 2 seconds, then nothing. Sound works normally through computer (Mac Studio) speakers. Switching sound setting back to Studio Display results in sound for 2 seconds, a brief scratch-like sound, then no sound at all. Switching to the other Studio display gets same result - sound for 2 seconds, brief scratch-like sound, then silence. Switching back to computer (Mac Studio) speakers results in normal sound.
I tried troubleshooting steps - connectors, switched Thunderbolt cables for both Studio Displays, power-down reboot, etc.
Could it be a bug in macOS 12.5? I just upgraded to macOS 12.5 about 24 hours ago.
