I have sound modules commented out in kernel config :
# Sound support
#device         sound           # Generic sound driver (required)
#device         snd_cmi         # CMedia CMI8338/CMI8738
#device         snd_csa         # Crystal Semiconductor CS461x/428x
#device         snd_emu10kx     # Creative SoundBlaster Live! and Audigy
#device         snd_es137x      # Ensoniq AudioPCI ES137x
#device         snd_hda         # Intel High Definition Audio
#device         snd_ich         # Intel, NVidia and other ICH AC'97 Audio
#device         snd_via8233     # VIA VT8233x Audio
#device         snd_uaudio      # USB Audio

However, if i plug in a USB mic the following kernel modules are loaded

8    1 0xffffffff81e44000 f344     snd_uaudio.ko
 9    2 0xffffffff81e54000 3dfdf    sound.ko

I do not seem to have any sound related options active in /boot/loader.conf or

This causes a problem when using ossv4.2 in ports, actually when a USB mic is
plugged in ...
(when using the oss v4.2 drivers, and you have them loaded into the kernel,
14    3 0xffffffff82086000 7b581    osscore.ko
15    1 0xffffffff81e44000 4360     oss_cmpci.ko
16    1 0xffffffff81e49000 214a0    oss_hdaudio.ko
... the machine instantly reboots. It would be good to either prevent sound.ko
from loading, or have the machine use the oss4.2 driver instead.

 Any hints or suggestions appreciated.
