sound not working on studio display

I have just spoken with Apple tech support. This is an early known issue. The fix is to unplug the Studio Display from power and disconnect the Thunderbolt cable from the Mac Studio, wait a minute, reconnect, and restart. Mic and sound work again. Reportedly, this issue does not recur once this fix is applied but if it does at least I now know how to, at least temporarily, fix it.

OOOPS! I didn't see the fix above. You have it!

Hi Infantrytrophy,

We understand you are having audio issues with your external speakers. Take a look at the section in this article for "If you’re trying to listen through your display’s built-in speakers" to help correct the issue.

If you can’t hear sound from your Mac speakers

Have a nice day.

I have exactly the same issue and I haven't upgraded to OS12.5. In addition, the Studio Display built-in microphone cuts out at the same time. Like Infantrytrophy, I have tried rebooting, switch cables and ports, power-down reboot but the problem persists. And the "If you’re trying to listen through your display’s built-in speakers" doesn't help.

Yeah, I have this same issue as well. Audio will play for a few seconds then it quits. This Display should be recalled and money refunded to the customers. The Audio doesn't work and the webcam has never worked well. The product is an over priced disappointment.

I've tried all the options of turning off the display and unplugging it for over an hour and then overnight with no change in audio cutting out on the Displays and I have two of them. I've tried Apple's options for the preferences without any change (which for those of use that have used Macs for a long time is just plain insulting).

I recently upgraded to Monterey 12.5 and it started right after that, within about 4 days. Prior to that I had NO issues.

One Display will intermittently work for like 30 seconds and then it makes a scratchy sound and it's just gone. I notice if it does start to work once I have plugged them back in --- as soon as I try to use the wireless trackpad or wireless keyboard the audio immediately cuts out and is permanently gone again.

I can do airplay or use the Studio speakers without issue so this is definitely a Display issue. The music plays fine on my Samsung TV using airplay with my Bose speaker.

I need to edit videos and this is getting frustrating. Why'd I spend so much Apple? Are you now putting out crap like Microsoft always has???? This is not good quality control.

Genius - now working perfectly. Thank you very much.

Same EXACT issue. Microphone is broken too. Go to the sound control panel and look at the mic input. Works for two seconds and then seems to be picking up random repeating non-existent sounds.
