it has though, at least according to most phone makers
the average person (me included) isn't bothered by the minimal loss of quality and latency, at least on the move
Bluetooth has replaced the aux port
i held out for quite a while, but i got a shokz bone conducing headset about five years ago and i had to admit, the sound quality is pretty good, so i got a fairbud xl more recently and they both work great with my phone. i still use a wired headset and mic with my pc though
i started on mint, with a 2080, played through hl alyx (with one weird issue - when i had my old xbox 360 controller plugged in, alyx and vr home couldn't start, but that was a few years ago, maybe it's not an issue any more).
which is to say, the index is not the issue, most vr games don't have a native linux version, so you have to rely on proton, and especially with nvidia cards they're far from guaranteed to run
but they also sell an official, better quality one, 1080p, without the flower
