Err, I don't see anywhere in your message where you disabled it. You would
need to add 'mixer_enable="NO"' to /etc/rc.conf. The hints are honored in
the mixer_init() function in sys/dev/sound/pcm/mixer.c here:
for (i = 0; i < SOUND_MIXER_NRDEVICES; i++) {
v = snd_mixerdefaults[i];
if (resource_int_value(device_get_name(dev),
device_get_unit(dev), snd_mixernames[i], &val) == 0) {
if (val >= 0 && val <= 100) {
v = (u_int16_t) val;
}
}
mixer_set(m, i, v | (v << 8));
}
