Front right and left speakers problems


I've had my Dell 5650 5.1 system for about 2 yrs now and now it started giving up. I was playing a videogame yesterday and i noticed that the sound from the front left and right speakers is very low and i can barely hear it. I tried adjusting the volume of the single speakers and installing the drivers but still no difference. The other speakers work perfectly and are loud but from those i cant hear anyting almost. Does anyone have the same problem and have a solution? thank you

    after trying the speakers on an ipod i noticed they worked fine, and after trying the different channels i noticed that when i plug the speakers in the front channel home there is a weird noise coming from the speakers, like they are blown, but with the other channel holes i dont have that problem. so could it be a hardware problem or drivers? i reinstalled the drivers yesterday though and doesnt seem to have worked.

Sounds like my problem almost exactly... I had to rip my sub-woofer apart and found out it was really bad wiring. Get to soldering if you can and replace the wires like I will have to do one day. *sigh*
The only think I'm looking for is a wiring diagram for inside the sub-woofer. Poking around online you can range from $35ish to $75ish. Depends on if you want to get your hands dirty or not. My origianl post was

This is going to have to be a solution in the don't rate until we have some kind of end-result.

Connect the speakers to a different device such as an MP3 player or a Nintendo DS. See if the speakers still cease to work. If they work just fine with a different device, then consider that it may not be the speakers...but a problem with the sound system in your PC.

Perhaps the sound configuration in Windows is disrupted. Perhaps the driver settings for your soundcard in your PC are corrupted. (A complete reinstallation of Windows with a fresh installation of the sound drivers would probably prove this theory right or wrong.)

Perhaps there is a problem with the FRONT CHANNEL hole on the sound system on the rear of your PC. You could check that by plugging the REAR channel of the speakers into the FRONT channel on the PC.

And lastly...there could be a break or a short in the cable of the speakers. You could always test another set of speakers with each sound channel and see if that might be the possible issue.

If the sound card in the PC turns out to be the problem, then install a different sound card. If the soundcard in your PC is currently the onboard one, then disable it in the BIOS before installing the new card.

Let us hear the results before we do any rating. Unless of course you're able to fix it with the data given. :)

    The more likely cause of the two problems you propose is that it's a
    hardware issue. (Not to say that it couldn't be ill-configured drivers
    or audio settings in Windows.)

    I would try a different soundcard to test this theory. If you happen
    to have an extra PCI soundcard laying around, install it in your
    machine, install the driver software for it and see what kind of
    results you can get. (Borrow one from a friend if you don't have one?)

    Quite honestly, the only other way to really tell is to either upgrade
    or roll back your drivers to different versions other than the one
    you're using...or reinstall Windows all together.

    But more often than not, when I run into this kind of issue, I find that it's usually an issue with the onboard sound hardware.

    Certain variables you might look at are whether or not you've installed
    new hardware or audio software recently. Every now and then, you may
    experience conflicts with new hardware. This could cause issues with
    ANY hardware in your system. Whether it be an audio adapter, network
    adapter or graphics card. (This time it just chose your audio
    system.) If that's the case, remove any newly-installed hardware and
    see what kind of results you get.

    Same thing with any software you've installed. Such as audio software, especially.

    One other minor thing to note... Check to make sure that any unused
    microphone ports are MUTED through your audio control panel. I've had
    MANY problems with those. (Especially in Linux.) They tend to create
    constant interference until you disable them by muting the microphone

    So check your driver version numbers through your Device Manager and
    compare them against the audio device manufacturer's website and the
    current drivers they have listed there.

    Note: Most onboard audio is done by Realtek.They
    list their drivers by version number which helps in this scenario. It
    may be listed as a Dell onboard or whatever...but the chip itself is
    most likely Realtek. You can see the soundchip on your PC's
    motherboard near the back end of the PCI slots. If you see a little
    electronic-looking crab on the chip, it's Realtek's AC'97 codec. The
    model number will show on the chip. You can always write that down and
    Google it to confirm that. (ALSO...if it says "Soundmax" on it, it's
    STILL Realtek.)

    Let us know further. I'll continue watching this thread. :)

How can I hook up the 5650 system to my lap top?

The laptop has one RT/Left mini port on the side or up front. You may require and adapter to a larger stereo plug if the Mini Adapter is too small for the speaker line input. If you have Two wires to the speakers and no Mini-Plug, you need Converter from Mini Plug to Right and Left Ports. Best you take it with you to RadioShack and they will match up the adapter you need then and teher.

Rear speakers not working

You might not plug speaker cables correctly in the PC board. The right way is to plug the Rear speaker cable in the middle slot and insert other (Front) speaker cable in just right adjacent to the Rear cable. The left one is the Mic Slot.

Only two speaker are playing sounds

I'm using Windows 7 with Sound Blaster Audigy 2 and I had to; right click the speaker icon, left click "Playback devices", left click speakers, in lower left of box left click "Configure", then left click 5.1 surround. And of course there's more. Go into programs and open the Sound Blaster "Audio Console" and left click "CMSS 3D" and look under "CMSS Modes" , if OFF is listed in the box click on the down arrow and change it to CMSS. Now all speakers work just fine.

Dell 5650 Speakers on Gateway DX4200

the speakers should have a stereo jack on a wire which would be the out put, if it is a surround sound speaker system then it most likely will have a few wires, if your computer has only one stereo jack input then the green cable would be the one you would connect in most cases, if it has 3 or 6 then you would follow the colour on the jacks and match them up with the input on your computer. if you have done all this and doesnt work check if there is audio icon in the bottom left task bar and if you can use other speakers, if you can everthing should work, if not then check for drivers online.

Dell 5650 speaker wire adapter

As I understand it, this adapter is used ONLY to adapt a standard 2-channel stereo output to the 3, 1/8" plugs of the Dell 5650 5.1 system. These 3 plugs would normally plug into the front, rear, and center/sub outputs on a computer designed to output 5.1 channel sound.

To make this clear, what this means is that the output you get from your 2-channel stereo system, using this adapter with the Dell 5650 5.1 system, will NOT be full 5.1 surround will be 2-channel stereo signals intermixed so that it plays from the 5650 system through the Dell amplifiers and speakers...nothing more.

This cannot be over-emphasized. The adapter does NOT create true 5.1 sound from a 2-channel stereo output system.

If you are hoping to get true 5.1 output from a 2-channel stereo system, you will be disappointed.

All this adapter likely does is split/mix some of the 2-channel signal into the rear channel, and split/mix some of the SAME 2-channel signal into the center-sub channel, just so you will get some output from those speakers. There may be some low-pass filtering for the sub-woofer input.

It is almost certainly a very simple passive circuit consisting of resistors, capacitors, and possibly an audio transformer or two.

Look for circuit on Do-It-Yourself electronic sites and build it yourself...or you're almost certain to be ripped-off.

Both right speakers not working

Try to interchange the connections of left channel and the right channel. If there is sound now in the right channel and no sound in the left channel it means that you have problem in the sound card. Otherwise if the problem remains the same you have a defective speaker on your right speaker system but don't forget to take a second look on your speaker wiring.
