No sound from new Apple Vision Pro

Thought I'd post a thread about this, in case anyone has any insight that i might have missed. 

As per the title, I set up my AVP yesterday, and quickly realized that no sound was coming from the built in speakers. I tried to find all the possible volume controls and cranked them up. Looked around in the settings for any possible sound killers. Restarted the device a bunch of times, both a regular restart and a forced restart. 

I tried my Beats Studio earbuds, and they work, although the sound is really low in volume, much too low, even with everything cranked up. 

So, before returning these, wanted to know if anyone knows about any hidden "mute switch" or similar i might have missed?
