# original wedge session: vm_snd.sh boot (ES1370 + intel-hda), snd_es137x + snd_hda kldload'd,
#   dev.pcm.0.play.vchans=4, vchan clones /dev/dsp0.N active, root churn of
#   dev.pcm.0.play.{vchanrate,vchanformat} + dev.pcm.0.bitperfect
# QEMU 7.2.22 (Debian), -enable-kvm -m 4096 -smp 6, no host audio backend (ALSA init fails on host)
# reruns: vm.sh reset with-src -> vm_snd.sh -> kldload snd_es137x; kldload snd_hda
