Gigabyte UD5 Dolby Live encoding

Greetings all,

When researching my latest build, I wanted to have a machine that had the capability to do Dolby Live encoding on the fly for games and send the output to my receiver via SPDIF (no analog for me thanks). My last machine (which is still kicking after running 24/7 for the last five years) was built on an Abit NF7-S, which I also spec'd specifically for the nForce2's same ability to do live encoding.

Alas, with Crysis, the HD3850 could not keep up, so I just built an i7 system with a GTX 295. I chose the Gigabyte EX58-UD5 because it was one of only a handful of boards out there that could do dolby live encoding (or at least so I read) with its onboard ALC889A. I did not want an add-on X-fi.

The problem is... no joy. Blu-ray and DVD can pass through the spdif no problem, which is the easy part of course. But none of my games encode in surround. I can't find even find an encode tab or config in either the realtek driver or vista's sound control. Am I missing something here?

I've spent the better part of the day searching around for answers, but most hits relate to the x-fi only. Any help would be appreciated. I am not new to this business, but am I also not oblivious to forums that will scream back "search noob" for new members. So if I can provide any more info for those who can help, please ask.

Cheers.
 
Ok, I think I solved the problem. However, going against the scientific method, I changed two things at once :nono: so I don't know which made the difference, but I'm not inclined to roll anything back and find out.

- I upgraded to newer realtek drivers (although the ones that came with the UD5 weren't that old to begin with)

- But I also noticed that I only checking off 48k on the SPDIF sampling output and for some reason didn't check off 44. I started to doubt whether my five year old surround receiver only accepted 44, so I checked it off too.

Crysis comes out in Dolby 5.1 via digital out now :)
 
Weird how the X58 has the ALC889a, I'm almost certain the last EP35 they made had ALC889b. Heck of a difference in the settings between it and the like of IP35's onboard realtek, which I *think* is ALC888.
