5.1 surround troubles -- rear speakers not playing sound

By n3burgener

  1. I've been using the onboard audio/sound from my motherboard on my XP desktop for the past 4 years. I bought a 5.1 surround sound set of speakers from Logitech (x-530) about 3 years ago, but only used the FL, FR, and subwoofer, because my mobo doesn't support surround sound -- it doesn't have the rear / center+subwoofer jacks that my speakers need to plug into.

    Today I bought a Dynex 5.1 sound card from Best Buy ($30) -- opened my tower, popped the sound card into an available port, installed the drivers from the CD, restarted the computer, set the output to 5.1 in the Sounds and Audio Devices window from the control panel, in the "Audio Deck" (the software that came with the card) I set it to 6 channel, made sure all of the speakers were plugged into the subwoofer which connects to the front-right speaker, and plugged the green, black, and orange plugs from the FR speaker into the proper jacks on the sound card, turned some test music on....

    And it's just coming out of the same two front speakers and the subwoofer like it was when I was running just the mobo audio. I've tried a few DVDs with PowerDVD but likewise, the sound is not coming out of the rear or center speakers. Then again I'm using the free version, I think. At least, under the audio tab in configurations it doesn't have any settings that specify surround, just 2, 4, 5, 6, 7, or 8 speakers. I tried each setting, but there's never any sound coming from the rear speakers except a very faint and dull static noise (if I listen very carefully with the speaker up to my ear).

    Is there something I'm missing, like do I need to disable the motherboard's audio (it's an Asus, if that makes a difference, I bought it years ago and the box / manuals have long been misplaced)? Are the speakers responding from the sound card but the computer's responding from the mobo or something? The sound card's got jacks for "analog auxiliary audio in," "analog CD audio in," and "wavetable sub-board connector," but I don't believe I need to mess with any of that or plug anything else into the sound card (or do I?).

    I've done a few "dummy" tests, the usual double-checking cables and testing the jacks one by one. Using "Audio Deck" I was able to play a sample drum beat through each of the five speakers and subwoofer on cue, so I know that the speakers work fine. I'm beginning to think that the surround is functioning fine, I just don't have surround-compatible software or media?

    Perhaps I'm not looking for an actual, genuine surround-sound system coming from my 5.1 set up. Is it possible to just have the rear speakers mirror what the front speakers are playing? Like having a 2.1 system coming out of 4 speakers? Basically I just want to play games and music while being immersed in the sound, rather than have it coming at me. How can I do this?

    Or am I just making myself look like an ***** with my ignorance?

    Dynex is not a company known for quality in their products, so it may be simply that the sound card is of poor build quality. However, I think it is more likely that you simply do not have any surround capable games or programs. Since these programs do not support surround sound, nothing will come out of the rear speakers. I have experienced this problem with my Logitech X-540s when I use a program with no surround support.

    I just bought a Asus P5QL mobo and it has that Audio Desk crap software too. And so far I can only get my front speakers to play also. The only way I have been able to make it work is by uninstalling audio deck and picking the driver directory from the control panel to install the audio driver separately from the actual installation exe file, which includes that crappy "ADECK or Audio Deck" software.

    While ADECK was installed I looked under the configuration and it said rear speakers were enabled but no sound! So I did the test, and the test made the rear speakers work, but NO MUSIC!!! No sound coming from Media player and none from Windows start up or shut down process. But the "TEST" feature makes sound come from the rear. So i got it connected right..

    btw, without the ADECK or Audio Deck software, and when I pick out the drivers manually from the control panel to install the sound drivers, as I said I can get the rear speakers to work that way.. but the Sound has no bass! I guess thats ASUS and VIA's way of making HI DEF sound. just take out the BASS. Thanks a LOT! Thinking about returning this POS mobo with their so called "HI DEF SOUND".
