A note unrelated to the previous report.
On my 6.3/amd64 system I get a message similar to the following each
time I kldunload snd_hda:

kernel: hdac0: detached
kernel: Warning: memory type hdac leaked memory on destroy (7
allocations, 16832 bytes leaked).

Also several cycles of snd_hda unload/load lead to a complete freeze of
the system.
