Realtek and Logitech 5.1 Z906 = crap. Advice needed

I invested in nice new Logitech Z906 speakers for my computer and am sort of stuck. These speakers are not working with my computer. I don't know how to set it up, but it may not be a user error -- I think the drivers are the problem.

I'm using an MSI Z97 Gaming 5 motherboard (which supports up to 7.1, see this for a visual) with Realtek's HD Audio Manager (which I use to test the 5.1 speaker output) on Windows 8.1. I tried two identical motherboards and both had the same issue.

I've pretty much done everything imaginable, including calling my motherboard manufacturer and trying to work with Logitech. Basically, the speaker test (on the Z906) works and all speakers are properly identified by the Z906 system (which I have set up for 3D).

However, while the device seems to work in the standalone testing, sound only comes out of the computer in stereo (using all 5 speakers) with the green audio output cable on the standard Line In only (or, using the 5.1 options on my motherboard, the side/center speakers, but not properly). And the sound sounds nice (music, that is), but when I watch a movie, I don't hear voices if Windows is configured for 5.1! I just hear background sound. (I have to reconfigure Windows back to Stereo to hear voices.)

No matter what I do, I don't know how to use the orange and black cables on my motherboard. The orange and black cables are detected by the computer when I plug in. However, there is no sound when I use either cable. I've also tried Line In and Mic In slots for those. No sound ever comes from the orange and black wires no matter how it's configured with the Realtek program (e.g. telling Realtek's app it's the rear speaker, front speaker, or side speaker).

The green cable works as side speakers (RS on my motherboard), which is detected as a side speaker when plugged in. That sounds like a Windows or other drivers issue. But still, when I listen to anything, I hear partial sound in those three jacks.

When I do any test, including in the Windows Sound control panel under Playback > Configure, all I see is a red circle by L R - rear panel 3.5 mm jack. The RL / RR, C Sub, and SL RR are black. I also tested the speakers individually there many times.

I'm kind of stuck. When I called the manufacturer, they were guessing possible solutions with me. I called a second time and the other guy said "it's plug and play."

The only way I can hear voices again when watching a movie is putting my 5.1 speaker system on "stereo" in Windows :( Realtek has not responded to my email inquiry about their crappy drivers, as this is not the first time I've read about the issue:

http://forums.logitech.com/t5/Speakers/Logitech-Z906-5-1-Sound-Setup-Realtek/m-p/1349838

But nothing. So...did these people get dedicated sound cards? Or what? (And if I have to go that route, is the Audigy SE okay? I don't need super special sound. I just want 5.1 to work.)

Thanks.

Realtek does have a test. However, it never plays sound out of the appropriate speakers. I have already been through Step 4 (right click > Configure > change Stereo to 5.1) about a dozen times...

btw putting black in the rear speakers, orange for center, and green on the side speakers means I get no sound coming out of anything if Windows is configured for a 5.1 setup or even a stereo setup.

Well that sucks.
Another thought is: can you use optical cable? Let speakers controller decode the digital sound.
Audigy SE would work, but its signal to nose ratio is not the greatest.
I have xfi and similar speakers, z5500. Never had similar problem. Creative's driver don't do the auto detect cable BS. Plus they have option to turn surround for stereo sources, so that everything goes 4.1 or 5.1

I guess I'll look into the optical cable method. Annoying, but I hope it does the trick... how would the computer detect 5.1 though? Forgive me, this is where I become a newbie as I don't know a thing about audio out of the digital spectrum :)

Do all the speakers respond correctly when you put the system into test mode?

I think optimal for your setup is "no effect" on the Logitech side, letting Windows and the Realtek drivers decide the mode of your choice.

with optical, you will have to set up one of standards to use - PCM stereo or Dolby Digital 5.1. Obviously you want second. Your speakers will then decode the signal and send it to 5 speakers.

Where do I do that? What types of cables?

@ketchup79 hi again :) (This is the latest problem!) - and no. They don't work in test mode at all, even with "defaults."

Okay, so I have an SPDIF cable I just tried.

I plugged the red/white into the back of the subwoofer of the Z906 and I plugged the other jack into the Line Out on the motherboard. And no sound...

Did I do it wrong?

So, let's break this down a little.

Control panel, sound, playback tab. What item is showing the green checkmark? For setup in your original post, it should be Realtek High Definition audio (or something very similar.)

If you hit the configure tab, what mode it selected? Try the modes your speakers support and see if they are correct. If they are not, I would recommend uninstalling and reinstalling the later audio drivers from here:
http://us.msi.com/support/mb/Z97-GAMING-5.html#down-driver&Win8.1 64
and try again.

@fralexandr: I tried room/speaker fill a long time ago. The problem is those are enhancements to try after you get test mode working. If I don't have test mode working, those enhancements are fruitless.

@ketchup79: the checkmarked item is Speakers, a Realtek High Definition Audio device. Correct.

Right now, the mode selected when I hit Configure is Stereo because when I have it on 5.1, no sound comes out.

And I've uninstalled/reinstalled many times. In fact, I spoke on the phone with MSI and they told me to get the latest drivers from Realtek's website "because Realtek has the newest ones always." Well, guess what? Realtek did not have the newest ones; MSI did!

when you use optical cable, make sure you set up to SPDIF out under Sound in control panel. In Properties, you can again select which formats are supported, there is even test button.

Do you maybe have graphics card that has its own HDMI audio out?

Oh, I do have HDMI out on my video card, btw.

I don't think my motherboard supports SPDIF...maybe that's why it's not working?

it doesn't. I just looked at the manual. Only analog speakers. WTF!? My no frills intel board has it.

So it is either make the realtek hd audio manager work, or get the sound card.

Seriously, onboard sound is ok when you use optical cable, but analog output is poor and for such high end speakers, you gotta use discrete sound card.

i doubt that audigy se is sufficient though. You'd want something better that works for sure for your speakers.

I'd love to get the HD Audio Manager working, but I can't figure out how to do so for the life of me. I emailed them but they haven't read it yet. Apparently they're known not to be responsive. Logitech support even blew me off because they said it was my responsibility despite forum posts dating back to 2012 describing this exact issue, of problems with their setup and Realtek. :/

I have my green jack currently plugged into the center speaker port - I also have it configured for center/subwoofer out. When I play test sound, I hear the subwoofer sound on one of the other speakers, not the subwoofer.

How annoying. And if the green jack goes in the the side speaker jack, I hear sound in the same two speakers. But if I plug it into the rear speaker jack, nothing comes out.

That statement gives a strong impression that something is being wired/ connected incorrectly, or something came wired incorrectly. If the speakers do not run the built-in test correctly (leaving the computer out of the equation), I would recomnend returning them.

Right, it does, per the below:

But I'm still thinking this is a Realtek issue. I'm reading too much about difficulties configuring with Realtek in the equation.

What other thoughts do you have?

3D. You said further up that you weren't. I really don't think you want to be using that speaker effect. At least not until you get things working correctly. No effect would be my suggestion. I wonder if it would be worth getting a cheap 5.1 sound card for the task if you still can't get things working right.
