When I put only "hw.snd.hdac.msi.enable=0" into loader.conf, I can't
query this value:

$ sysctl hw.snd
sysctl: unknown oid 'hw.snd'

After "kldload snd_hda" I get:

$ sysctl hw.snd
hw.snd.report_soft_formats: 1
hw.snd.targetirqrate: 32
hw.snd.verbose: 1
hw.snd.maxautovchans: 4
hw.snd.pcm0.buffersize: 16384
hw.snd.pcm0.vchans: 1
hw.snd.pcm0.polling: 0
hw.snd.pcm0.polling_interval: 250
hw.snd.pcm1.buffersize: 16384
hw.snd.pcm1.polling: 0
hw.snd.pcm1.polling_interval: 250

and ugly sound.

When I then add 'snd_hda_load="YES"' to loader.conf, I also see
nothing about msi but as before:

$ sysctl hw.snd
hw.snd.report_soft_formats: 1
hw.snd.targetirqrate: 32
hw.snd.verbose: 1
hw.snd.maxautovchans: 4
hw.snd.pcm0.buffersize: 16384
hw.snd.pcm0.polling: 0
hw.snd.pcm0.polling_interval: 250
hw.snd.pcm1.buffersize: 16384
hw.snd.pcm1.vchans: 1
hw.snd.pcm1.polling: 0
hw.snd.pcm1.polling_interval: 250

and I get no sound but an error message from mplayer:
