Hey everyone,

I am attempting to connect my pc to my a/v receiver and get 5.1 dolby, but for some reason I can only get stereo sound. I have been reading that there is no driver for the realtek HD audio to support 5.1, but that's ridiculous, right? I mean, what's the point of having the HD audio output if there is no driver to support HD audio?

Does anyone have a solution to this problem? I installed the latest drivers from Gigabyte's website, should I look on Realtek's?

Thanks

Realtek HD audio supports 5.1 sound, But you need to supply it with a 5.1 source. What type of source are you trying to use and how are you making the connection to your a/v receiver?
May 21, 2008 5:17:47 PM

well, when I use the 3D audio demo in the realtek/gigabyte control panel thing it only has sound coming out of the front two speakers, no center, sub, or rear. I'm connecting thruogh a digital optical cable. Also when I play call of duty I set the sound to 5.1 but its still stereo.

If I go into the windows volume control thing it shows vol controls for all the surround channels in analog, but the s/pdif vol control is gray. Also the receiver displays "stereo" as opposed to "dolby dig 5.1"

On my gigabyte board (GA-MA69GM-S2H), I had to go into the Realtek UI and enable 5.1 DTS to get surround sound for all sources. DVD's with DD still go to the receiver as DD 5.1 with this setting. Does your receiver support DTS?

Where is this option in the UI? All i can select is 2-8channel speaker. Yes my receiver supports dolby digital/DTS.

I remember some(or all?) creative cards did not support surround sound through their digital outputs(unless it was surround sound from a dvd).
Maybe realtek might have the same issue, though I am no audio expert so I could be completely wrong. :p

hmmm, I will try a DVD-- hopefully something happens. Thanks

EDIT: Nope, same thing... damn

I'll try to get some screen caps when I get home and post back. I can't remember exactly where the DTS 5.1 option is located.
May 21, 2008 7:25:49 PM

thanks that would be awesome! I am really looking forward to getting this thing straight...
May 21, 2008 7:38:57 PM

Sorry to disappoint, but the DS3L doesn't do Dolby Digital Live or DTS Connect. I found out the hard way as well :( 

Hell, that's my first double post ever. I have no idea how that happened...

One more thing, which operating system are you using? XP does not support 5.1 sound without the addition of the proper CODEC even with DVD's
May 21, 2008 7:52:00 PM

Yeah Im using XP, there's definitely no support for 5.1? Why is there the optical audio port then?? I dont understand--there must be some way!

A long time ago...in a galaxy far far away...

Optical out was for 2-channel stereo only.

With XP I know for 5.1 sound from DVDs you need to buy a copy of WinDVD or PowerDVD to get the CODEC to play 5.1 sound. Those free copys that come with DVD drives are not full versions of the software and do not include the needed CODEC. That is most likely the reason your S/PDIF volume control is grayed out. With the latest version of Windows Media Player you can go online thru Media Player and buy the needed CODEC from WinDVD or PowerDVD without buying the complete softwar package from them. Saves you a little money. Once you have the CODEC the computer will be able to play DVD's in 5.1 sound, don't know about games and music well its a stereo source and will play that way unless you use some type of expander for simulated 5.1 sound which doesn't really sound that great.
May 21, 2008 10:36:49 PM

well that sucks. I can still get it through analog though right? my 5.1 computer speakers are in the other room (I dont have a monitor in there yet) so I havent tried those yet. Green, black and orange plugs mean semi-surround right--like front channel, rear channel, and sub/center channel?
May 21, 2008 11:40:58 PM

the optical output supports 5.1 but your still going to need a 5.1 source

Before installing the audio driver, make sure the "Microsoft UAA Bus driver for High Definition
Audio" has been installed from the motherboard driver disk and your operating system has
been updated with the latest Service Pack for Windows.
(Note) 2/4/5.1/7.1-Channel Audio Configurations:
Refer to the following for multi-channel speaker configurations.
• 2-channel audio: Headphone or Line out.
• 4-channel audio: Front speaker out and Rear speaker out.
• 5.1-channel audio: Front speaker out, Rear speaker out, and Center/Subwoofer speaker out.
• 7.1-channel audio: Front speaker out, Rear speaker out, Center/Subwoofer speaker out, and Side speaker out.

Found on page 71 of your Manual.^

I have heard that SP3 takes out the Microsoft UAA Bus driver for High Definition Audio in some cases and it had to be reinstalled by exploring the installation drivers and utilities disk.

Did you install SP3 by any chance? Im sure you did if you have XP.
Look in your device manager...any Yellow Marks?

Why wont it do 5.1 in COD4 when I set it to 5.1 mode in the game? Do I need some codec or something still?
May 21, 2008 11:58:05 PM

^ Nah, I dont have sp3 installed just sp2. I did read that btw, and no yellow ? -- that UAA bus is there...

Without DDL or DTS Connect you can't get surround sound in games through the digital outputs. Check the links I posted above :) 

Technically the Realtek ALC888 supports DDL and I think DTS Connect also, but it isn't enabled on the DS3L. I've spent many hours trying to "unlock" this functionality, but it doesn't seem possible.
May 22, 2008 1:50:50 AM

Wow, that's too bad. Maybe I will call Gigabyte tomorrow to confirm this, maybe they will tell us how to get it? Have you tried calling their tech support before? hmmm, damn.
May 22, 2008 2:40:43 AM

I got Dolby Digital now in movies! I had to install AC3 Filter: http://ac3filter.net/

well, that's a step at least. Now I'll check games and stuff and report. Nice.
May 22, 2008 3:49:37 AM

Ive got the same prob on my Asus board using coax dig out.
Same realtek HD.

Solution: Set number of speakers to 2.
My receiver tends to sort the 5.1 channels out just fine.
The demo DOES send the right sounds to the right speakers when u set it to 2 speakers.

Give it a go.
May 22, 2008 4:29:05 AM

mrmez-

That actually worked! who would have thought? Do you have the AC3 filter installed or should I get rid of that? Nice little trick thanks!
May 22, 2008 8:50:00 AM

Np, glad it helped :D 
Dont have that AC3 filter, tho i may try it.

Next problem i have....
Digital output on the mobo (coax or opti) can only put out ~750Kbs. I need at least 1,500Kbs for bluray. This can only be achieved by HDMI 1.3a.

My amp has no hdmi inputs. Can go to tv, then how do i get the sound back to the amp?

Fubar i tells ya.

I have similar problem. ASUS P5Q Pro motherboard. Yellow coaxial digital output in the back. My Foxconn had an orange one in the past. Does the color matter? I am using Vista and when I go to the properties for that output, the only available choice for defaul output is stereo. So, no 5.1 DD going to my receiver. I used Realtek drivers from ASUS website. My only choice is to re-image the machine and install Realtek drivers from their website. Any ideas?
July 25, 2008 4:06:26 PM

Once again, no Dolby Digital Live or DTS Connect = no 5.1 in games over the digital outputs. I don't see either of those features listed on ASUS's specs for the P5Q Pro (or any of their motherboards for that matter), so I assume it lacks them both. Of course this is an assumption and I may be wrong, but it's hard to tell; information on these two critical features can be surprisingly hard to come by..

Anyway, without DD Live or DTS C you have to use the analogue outputs to get surround in games.

^What about the ASUS Xonar series? I've read some stellar reviews of the DX.
July 25, 2008 6:09:36 PM

I've heard good things about them too, I just neglected to add them. I'd say the Xonar, the Prelude, ...and the X-Fi Elite Pro are probably the top consumer boards right now, except that Creative wants you to bend over while they have their way with you to get DDL, shame on them.
July 25, 2008 8:15:24 PM

As much as I hate broken compatibility with old games, I'm glad Vista freed us from the iron grip of EAX. Creative deserves everything it is getting.
July 26, 2008 1:25:24 PM

I had DD 5.1 sound on my old 590SLI motherboard. They all advertize HD audio these days and digital coaxial/optical outs. I thought that meant DD5.1. I guess I was wrong. I can't believe my old motherboard had it, and the newest Intel P45 doesn't. I re-imaged my machine, installed Realtek drivers and still nothing. I set the playback device to realtek digital output, but in it's properties the only available formats are stereo. If anyone has a solution, please help.

Believe it; it's a licensing issue, not a technical limitation. The mobo manufacturer didn't pay the fee to enable DDL or DTS C even though the chipset supports it, so no 5.1 in games over the digital connections for you :p 
August 13, 2008 4:36:54 PM

a hint:

in earlier times this "no 5.1/real dts/dd on digital outputs" was a common problem .. it's not about technical issues,it's about licencing issues...

all the devices actually DO support 5.1/dts/dd through their digital outputs, but the device drivers dont...

luckily there are excellent individuals who write own genuine drivers which UNLOCK this feature
like he does... http://code.google.com/p/cmediadrivers/

i tested this with my old nightingale pro6 soundcard and FINALLY, in the year of 2008, i got real DTS sound through my coax digital outputs...

-
i also got a brand new EP45-DS3L, i havent tested the rear spdif output so far, it would be a freaking SHAME if this "problem" still existed.
if this is really still existant, get some old nightingale soundcard for 5 bucks off eg*y and install the genuine drivers to enjoy your 5.1
