RealTek AudioManger 3D-sound demo:
2ch: Audio from al speakers but the position is wrong.
6ch: Only front left and right speaker but position is good.
I got a 5.1 sound system (Logitech Z-5400) using Coax
RealTek driver 5.10.0.5628 (R1.94)
Speakers worked fine with my Augity 2 card (Coax).
I bought a RCA female and drilled a hole for it in one of the computers PCI cover plates. I then cut of the included SPDIF to VGA cable and connected it to the RCA female.
This means that the motherboards spdif GND is connected to the computer chassis. Maybe that interferes with the digital signal?
cpmee did you get 5.1 sound or only Stereo with spdif?
I get surround using RealTek analogue outputs but I use those for gaming and SPDIF to my TV (AE-500 projector).

off the topic how can you route the hdmi audio cable on the mobo to a coaxil output?..
Its easy, Ive done it and it works fine.
Just get an ordinary RCA cable (surely you have some hanging around from any stereo or tv package) and a tiny 2 pin plug from any old case. Connect together. (Technically the center plug goes to the spdif pin and the outer casing plug goes to gnd, but it will work no matter the polarity)
The 2 pin plug then goes to the motherboard HDMI_SPDIF header, only using the spdif and gnd pins. Do not use the +5v pin.
The only downside I have is that it increases the RF interference to certain TV channels when its plugged in. Unplugging it stops the interference. I should get a heavier shielded RCA cable someday, but its not a priority. Also my TV is only 2 feet from my computer and it has an aluminum case, so if yours is further and a steel case, you should have no interference.
After everything is connected, then go into the Realtek HD Audio Manager > Audio I/O > Digital and set your SPDIF settings. Make sure your receiver is set to receive coaxial input.
