Hi,
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
automatically:
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
/etc/rc.conf
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,
ie
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.
Thanks,
