Building kernel with no sound

[Alexander Sieg]

Hey,
iÂŽm trying to build a custom kernel with no sound support build in.

This is my make.conf:
MALLOC_PRODUCTION=true
KERNCONF=MYKERNEL #GENERIC-NODEBUG
DEVELOPER=yes

and this is my kernel configuration:
include GENERIC-NODEBUG

ident MYKERNEL

nodevice sound # Generic sound driver (required)
nodevice snd_es137x # Ensoniq AUdioPCI ES137x
nodevice snd_hda # Intel High Definition Audio
nodevice snd_ich # Intel, Nvidia and other ICH AC'97 audio
nodevice snd_uaudio # USB Audio
nodevice snd_via8233 # VIA VT823x Audio


The problem is when i try to compile it with "make buildkernel" the
build process starts, but it stop with the error that it canÂŽt find the
header file "channel_if.h".

/usr/src/sys/dev/sound/pcm/channel.h:256:10: fatal error: 'channel_if.h' file not found
#include "channel_if.h"
^~~~~~~~~~~~~~

The intention behind the custom kernel is to try 'oss' form the
ports tree.

​You're missing a few of the sound drivers. Here's the section from
GENERIC on 11.1 for sound (it's the same for 10.4 and 12-CURRENT):

​# 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

​So you need to add nodevice entries for all the ones that you are missing
(snd_cmi, snd_cma, snd_emu10kx).​

Always check the kernel config file you are including to see what you need
to exclude via nodevice. :)
