Instagram Story music plays silent on Meta glasses clips only (iPhone clips fine)

I posted six Story videos to Instagram today, all with the same song picked inside Instagram (Dylan LeBlanc – Coyote). The three shot on my iPhone play the music fine. The three shot on my Oakley Meta glasses show the song sticker but play completely silent, with no speaker icon at all, and Instagram tags one of them "Oakley Meta glasses" in the corner. Same result on two different phones.

I'd rather post straight from the glasses without re-encoding anything. Has anyone else run into this since Instagram added the new glasses editing tools to Stories? Is there a fix, or a way of sharing that keeps the music?

Screenshots attached: clip 2 is iPhone (sound), clips 4 and 5 are glasses (silent).
