I don’t know much about DAWs beyond messing around in them but I have a w11 VM with a recent nvidia card passed through (VFIO) and latency is not a concern in the slightest.
Was your experience with no graphical acceleration? It makes a world of difference. KVM/QEMU is also a good bit more performant than something like virtualbox if that’s your frame of reference
Ive been wanting a mini PC for a while now, enjoy your beelink!
I have a w11 KVM + nvidia card, even bypassed EAC when it detected the VM and refused to start
I use my iGPU in the Linux host and it’s fine. I only game in the VM for lots of reasons. You can swap them but I don’t have experience with that
The mic if you add it in VM hardware as passthrough USB will work on your host until the guest boots then it only works on guest.
For multi monitor just try and ask if you have specific problems
One tip is setup sunshine on your VM so you can quickly jump in from any moonlight device. Looking glass Is better but only works from the host pc
Lmk if you have other questions
