I read many posts regarding Shure MV7 doesn’t work at all on Linux: here, here and here.

It got me nervous as I already bought this on Amazon and return is not an option since I live in Vietnam.

However, when I receive the mic today, it just works, right out of the box, on Pop!_OS (v 21.04). The only thing different with the vanilla Pop!_OS distro is I switch to pirewire for audio instead of pulseaudio.

For those with the mic and struggle to get it to work, I strictly follow the setup instruction post here on Reddit. Many thanks to bob488.
