I would like an USB FM transmitter which shows up as an USB audio card.

You set the sound card output at your OS settings and everything it's broadcasted over FM.

I know some of them exist for bluetooth audio, but not for FM.

It would be cool to have this in one unit, but it's also easy to put together by combining two readily-available devices:

- a USB sound card with 3.5mm jack, and

- an FM transmitter module (which can usually be powered with 3v-12v, so should be able to work with 5v USB power

This is an interesting challenge, would be a great homebrew project.

(If I wasn't already neck deep in interesting challenges I would consider picking this one up)
