surround sound with FreeBSD
dmesg on FreeBSD 6.2-PRERELEASE shows the following sound system:
pcm0: <VIA VT8237> port 0xc400-0xc4ff irq 22 at device 17.5 on pci0
pcm0: <C-Media Electronics CMI9761 AC97 Codec>
This onboard sound system can output 5.1 surround sound. It has only
three female. In ordinary stereo operation they are used for mic in / spk
out / line in. The meaning of the females can be switched to rear /
front / center + sub.
Can this be done with FreeBSD or some software from the ports?
