What's P2?

That's dangerous. The reason it does that is because you're using the Default selection in OBS, which defers to the setting in Windows. The reason it's dangerous is because Windows can change that setting all by itself without telling you. It's assumed that you *want* to use a different device, and so it just quietly makes that happen...except you DON'T want it to happen here!

Always choose a specific device in OBS, never use Default.

Even showing that it's active the two, if I put in different audio tracks don't play together on Live.

The Tracks don't mix. Only one Track goes to the stream. You can record multiple Tracks, but you only hear one at a time. If you want to hear multiple things together, they need to be on the same Track.

Unless you *want* different simultaneous audio for some reason (live translation, descriptions for the visually impaired, etc.), and can produce that, just select Track 1 for everything and ignore the rest of them.
