When running FreeBSD on an arm64/aarch64 QEMU virtual machine, using the
Intel HD Audio Controller (ich6) (intel-hda), for example, and by
following the procedure in the handbook ("Setting Up the Sound Card"):
kldload snd_driver
The following error is shown:
KLD snd_driver.ko: depends on snd_cmi - not available or version mismatch
This is because the CMedia sound driver (snd_cmi) is only built for i386
and amd64.
Add the same guards to the snd_driver metadriver.
