the onboard header has both SPDIF-in and SPDIF-out and also 5V if i remember
SPDIF is just 2 wires (pins) - its a trivial matter to hook it up to a RCA
i took a "HDD LED header plug" from an old machine and soldered it to a RCA
plug. took all of about 3 minutes.

the Realtek ALC883 HDA is supported in ALSA. it works perfectly fine.

my system is an older Fedora Core 2 upgraded to Fedore Core 3 some time in the
past. i.e. quite old. :)
due to the mix of tuner cards i use (4 of them), i run a kernel.org kernel
(2.6.18-rc5 - was the most recent when i bought the motherboard) with
tip-of-tree DVB/V4L and top-of-tree svn ALSA at the time.

i use the libsamplerate as an asound plugin to ensure the h/w is always fed

probably - if the pinouts match..
