It doesn't work for me... See below.

I'm booting with the following script.

VM=freebsd12.1
ifconfig tap1 up
bhyve -AHP -s 0:0,hostbridge -s 1:0,lpc \
-s 2:0,virtio-net,tap1 -s 3:0,virtio-blk,./disk.img \
-c 1 -m 4096M \
-s 19,xhci,tablet \
-s 11,fbuf,tcp=0.0.0.0:5920,w=1280,h=1024,wait \
-s 20,hda,play=/dev/dsp0,rec=/dev/dsp0 \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \
$VM
bhyvectl --destroy --vm=$VM

I have the issue on my daily driver, a Thinkpad T430. But also tested on
my x220, same issue, only noise. However, sound works perfectly fine
on OpenSUSE guest.
