So...this is not really a use-case per-say as it is actually a thing I would like to do but can't at present...
Win 10 is lacking an ad2p sink and this means if I'm using it to play a windows-only game and want to stream from e.g. my phone to my computer, I can't (natively). Enter Linux, which mostly ignores most of the crazy crap from MS... and VirtualBox which can see my bluetooth adapter, relay to the audio outputs, problem solved (yay? - well I also had to modify a kernel parameter and some config files, but it worked at least)! So anyhow, the bluetooth stuff not working from qemu is a bit of a shame - VBox is bad at virtualizing stuff I guess unless the OS explicitly says "hey I support this!" and I was hoping to use a super-light-weight distro to solve my problem, not the mega-behemoths such as Manjaro, Ubuntu, Fedora... I'm not familiar with the project, so I don't know, but it seems like this shouldn't have changed very much, and probably should just work? The only way I know bit-rot happens at the protocol layer is that a bunch of developers made a bunch of changes they didn't have any business making, or the original code wasn't written very well to begin with... Anyhow, cheers. Hope to see BT live in Qemu again someday!
