No sound on VisionPro after mirroring VisionPro with MacBook

No sound on VisionPro after mirroring VisionPro with MacBook and stopping mirroring. Sound routing is only possible when mirroring to a MacBook. Unmirroring disables VisionPro sound altogether. I used to be able to choose whether to output sound to VisionPro or to the mirrored MacBook, but this is no longer possible.

The Vision Pro doesn't sound after a few reboots, and the MacBook doesn't sound after a few reboots. Suddenly I have to mirror to the macbook to get sound on the vision pro. How is this possible?

This is a recording of the symptoms of the current issue. As you can see, it is completely disabled so that you cannot select the speaker volume.

Sound plays well on my AirPods.

Only the Vision Pro speakers don't work. Why is this suddenly happening?

You shouldn't even try to do what is written in this post. https://www.macobserver.com/tips/how-to/why-is-there-no-sound-on-my-new-apple-vision-pro-heres-how-to-fix-it/

I'm in Korea, so I can't go to an Apple store in person to get an AS, so I've had 2 diagnostics done remotely via phone with an Apple US agent.

I even did a factory reset, but that didn't help, and was told that it was a software issue, that they recognized it as a core issue and were working to fix it, and that I should wait for the VisionOS update.

I can only hear the sound through my AirPods, which is inconvenient, but I'm glad to have Vision Pro nonetheless. Hopefully a software update will fix this soon.
