nforce2 digital audio output support? (or spdif support at all?)

[FreeBSD Prospect]

Hi!

I was searching for more info about support for DOLBY DIGITAL pass-through to 
a digital audio output, but nothing recent came up.

This matter seems to be a serious shortage in FreeBSD, because the only 
useable info which came up on www.google.com/bsd was concerning NetBSD 
(http://bsd-crew.de/index.php/5.1-Surround-Sound_mit_NetBSD, which is in 
German language). There something of an audio-layer is mentioned.

Is it really possible, that NetBSD is ahead of FreeBSD in that particular 
matter?

I have a workstation with Asus A7N8X-deluxe motherboard, which features the 
nforce2 chipset, and has an electrial digital audio output.

On my first few tests with FreeBSD 6.0 (-RELEASE), after loading the snd_ich 
driver, I got analog sound working, but the digital output was not recognized 
and did not show up in sysctl.

Any idea, if spdif support is already in -CURRENT, and if not, if somebody is 
working on that issue?
