qemu Audio Passthrough from FreeBSD VM to Void linux host

I have been attempting to get audio passthrough from a FreeBSD VM ( 13.0 ), running with virt-manager ( QEMU ), on Void Linux ( Latest, as of 3/09/21 ). My void setup is currently using Pulseaudio, and I know that FreeBSD uses OSS. I have attempted all the fixes I can find; config changes in virt-manager, the Arch wiki, so on and so forth. A list of solutions that I have tried is at the bottom.

Does anyone know to to enable sound passthrough from FreeBSD to Void?
Apologies if I have not provided enough information, I am happy to provide things if needed.
Thanks in advance.
