I got bluetooth to work. but with odd results.
i can connect my edifier bluetooth headphones to the vm bluetooth setting. it managed to pair.
at one point it disconnected, no idea why. so i click connect, and it connected back.
next issue is though audio plays there is HUGE lag. the music is barely constant and keeps breaking every few seconds. basically not really usable.
im wondering if its broke or something i did wrong 
This is what i added as device in the vm
pcie passthrough
0000:0e:00.0 ‘Network controller’: MT7922 802.11ax PCI Express Wireless Network Adapter by ‘MEDIATEK Corp.’
0000:12:00.1 ‘Audio device’: Rembrandt Radeon High Definition Audio Controller by ‘Advanced Micro Devices, Inc. [AMD/ATI]’
usb passthrough
controller type qemu-xhci
usb 1_6_usb audio micro star international
usb 1_7 wireless device (mediatek)
If i had to make a guess, i think the bluetooth was one or both of the usb passthrough.
proof that i at least got the bluetooth to show and pair/connect with. just that it wasn’t very stable 
as i said the audio was stuttery/laggy, and the volume was way too loud. i basically dont dare use it till i got that sorted out
PS: i also got the wireless to work, though i did not try to connect it to any wireless network (since im already connected wired). but it at least shows.
*update
I think maybe i need to install the motherboard antenna. ill see if that fixes it. brb
