My silly Lenovo has a wifi card whitelist: no upgrades. I need BT 5.2 for multipoint audio stuff, among other things

Thinking USB dongle or maybe USB tethered puck/base? With two ants preferably, go nuts with geofencing ie: angle of attack

I'm a little confused by all this aptx and audio-only stuff

Well not so much confused as not much interested...

Haven't dug real deep but all I'm finding is emphasis on audio and disclaimers about cell phones and other things it WON'T work with.

Any ideas?
