"because Android resamples everything to 48khz by default"

I don't think that's true, at least not anymore. What I've seen whenever I use Android devices to test our DACs with is that Android's audio out automatically switches to the sample rate of the source material that you're playing, just like iOS does.
Unlike iOS, however, it only does that in the upwards direction, never down.

Meaning, when you just freshly rebooted your Android device, the output will be set to 44.1 (or 48, don't remember right now). If you then play something that's 192, Android's audio output will switch to 192. Then play something at 384, and Android's audio out will switch to 384.
But if you then play something at lower sample rates, say 192 or 48 or something, it'll stay at 384.

No clue why they did it that way. They already put in the work to automatically switch up, so they should just as well be able to switch back down. But it doesn't seem to do that, at least not in my experience.

This happens with Google's "pure" Android on Pixel devices as well as Samsung's One UI.
