>Description:
kernel compile fails with:

config: Error: device "snd_sb" is unknown
config: Error: device "snd_sb" does not take a count
config: 2 errors
*** Error code 1

I have in my kernel config:

device          sound
device          snd_sbc
device          snd_sb16
device          joy

Note, that the error message is "snd_sb" despite the "snd_sb16" in the kernel conf.

If there is only 
device          sound
device          snd_sbc
device          joy
in the kernel config, the compile succeeds and dmesg gives:
# dmesg |grep sbc
sbc0: <Creative SB AWE64 Gold> at port 0x388-0x38b,0x330-0x331,0x220-0x22f irq 5 drq 5,1 on isa0
sbc0: [GIANT-LOCKED]

but there are no sound devices in /dev and /dev/sndstat gives only: 
# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:

With this kernel, loading the module snd_sb16 works in part: the sound devices in /dev appear (which is the reason I tried to compile snd_sb16 into the kernel), but sound nevertheless fails (the AWE64 might not be really SB16 compatible; snd_sbc and pcm only were sufficient before the pcm->sound change).

So before the change to "device sound" I simply had 
device pcm
device sbc
in my kernel config and everything worked like expected. The hardware itself is o.k., Linux and Win still produce sound.


>How-To-Repeat:
cvsup to the latest CURRENT sources, put "device snd_sb16" into your kernel conf, "cd /usr/src && make buildworld &&make kernel"
