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

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

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

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

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 ?
