Default problem with Virtual Sound Channels in FreeBSD 7

Hi I have installed FreeBSD 7.0-RELEASE with custom modified kernel. If I try to utilize multiple sound sources like say freebsd handbook in this section and when I try to set this two nobs

Code:
sysctl hw.snd.pcm0.vchans=4
sysctl hw.snd.maxautovchans=4
sysctl gives me an error message.

Code:
[root@cormallon /]# sysctl hw.snd.pcm0.vchans=4
sysctl: unknown oid 'hw.snd.pcm0.vchans'
the second sysctl nob is corectly write

Code:
[root@cormallon /]# sysctl hw.snd.maxautovchans=4
hw.snd.maxautovchans: 4 -> 4
I have an intel ich soundcard which is corectly recognized by kernel

Code:
pcm0: <Intel ICH6 (82801FB)> port 0x1c00-0x1cff,0x1880-0x18bf mem 0xb0000800-0xb00009ff,0xb0000400-0xb00004ff irq 22 at device 30.2 on pci0
pcm0: [ITHREAD]
pcm0: <Analog Devices AD1981B AC97 Codec>
so any idea what is wrong ?

Code:
FreeBSD cormallon.local.bsd 7.0-RELEASE-p3 FreeBSD 7.0-RELEASE-p3 #0: Mon Jul 14 21:02:05 CEST 2008     casper@comallon.local.bsd:/usr/obj/usr/src/sys/CORMALLON  i386
thx casper007

On FreeBSD 7 you dont need to change such sysctl variables.

Code:
hw.snd.maxautovchans: 16
dev.pcm.0.play.vchans: 1
dev.pcm.0.play.vchanrate: 48000
dev.pcm.0.play.vchanformat: s16le
dev.pcm.0.rec.vchans: 1
dev.pcm.0.rec.vchanrate: 48000
dev.pcm.0.rec.vchanformat: s16le

Virtual channels on 7 are automatically created when needed:

% ls /dev/dsp0.?

% ls /dev/dsp0.{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}

% ls /dev/dsp0.?
