The kernel doesn't build with snd_uaudio.ko if there is sound.ko missing.
GENERIC kernel cannot load modules osscore.ko and oss_hdaudio.ko with
sound.ko either built in the kernel or loaded as a module. When I tried to
load snd_uaudio.ko manually, with both osscore.ko and oss_hdaudio.ko
loaded, exactly the same happened, as if I plugged in my camera.
I plugged in the camera after 50s of running (practically immediately after
boot). This is the kernel message on my monitor. I enabled dumpdev=3D"AUTO"
in my /etc/rc.conf, to get the full output, but there was no file in
/var/log showing anything, so I just wrote here what I managed to see on
the screen:
