The speakers are connected correctly. However sound only comes from speaker.

Troubleshoot this issue. Here are some steps you can follow:

Check Speaker Connections:
Ensure that the rear surround speakers are properly connected to the Audio/Video (A/V) receiver.
If applicable to your model, verify that the A/B speaker selector is set correctly. If the speakers are connected to the A speaker connection, the selector must be set to the A position.

Test Tone Operation:
Perform a test tone operation to check if the speakers are functioning correctly.
Increase the rear speaker volume or adjust the surround speaker settings to the maximum level.

Speaker Size Settings:
Try selecting a different size (small or large) for the rear surround speakers in the menu.
Surround Sound Mode:
Verify that the A/V receiver is set to a surround sound mode.
For Dolby ProLogic surround sound, ensure that the center-channel mode is set to NORMAL or WIDE.
If your source is a DVD or Blu-ray Disc player, check that surround sound is enabled in the player's menu.
The audio being received must be multi-channel.

Different Surround Sound Mode:
Try setting the A/V receiver to a different surround sound mode.
Source Content:
Verify that the source you are playing is encoded in surround sound.
Note that during periods of mainly dialog, most of the sound may come from the center speaker only, with audio coming out of the rear speakers when there is background or ambient noise.

Factory Reset:
Reset the unit back to factory default settings (consult your operating instructions for model-specific steps).
If applicable, follow the steps for calibrating the appropriate settings automatically after connecting the calibration microphone device.

Speaker Wires and Replacement:
Check and replace the speaker wires if necessary.
Consider connecting a different pair of speakers to see if the issue persists.
If you've tried these steps and the problem remains unresolved, I recommend seeking professional service.

Try the speakers in some other desktop/laptop computer, to verify that the speakers are working correctly.

Try a different pair of speakers in your computer, to see if your computer is correctly sending "sound" through that 'green' port.

Try using headphones in the socket that the speakers are connected to. If you hear sound on the headphones then the socket is working. If no sound then check you are using the correct socket - usually coloured lght green.

The source. Is it connected to a computer - the sound device might not be set up correctly?

check the speaker.. could be burned or open connection

Wiring speakers with reverse polarity doesnt have adverse effects. It cant give distorted sound. Seems like the wiring from the head unit to the speaker might be at fault. For testing purposes, connect the speaker directly to the head unit, bypassing, the car wiring. If the sound comes out alright, you have to replace the car wiring. If it is still distorted, speaker might be at fault. Try with a different speaker.

Check the back of the computer. Typically this caused when the connection is loose or the speakers are plugged in to the wrong jack. The correct jack on a Dell is usually a light green color. The Microphone is pink, etc.

Good Morning:


Hope that you are wellJ

Connecting the speakers correctly seems to be the biggest issue.

Be sure that you are not set to stereo

You must have at least a 6 channel card.

Also:

After verifying that the connections are made correctly, the sound card needs to be checked to make sure it is setup correctly. There are many sound card manufacturers so we cannot possibly cover every make and model. We recommend contacting the manufacturer of the sound card to make sure the sound card is setup correctly for use with analog 5.1 speaker systems.

When a software DVD player is being used to watch a DVD, the audio output needs to be set to surround sound mode. Please refer to the user manual for the software DVD player to check the settings.
Many DVDs have more than 1 sound format available. Just as the sound card and the software DVD player, the DVD itself has to be set to the correct sound format.

Finally you can test to see if the speakers are working correctly by plugging the front channel cable coming from the sound card to the rear channel connector on the subwoofer. If sound comes out of the rear speakers, then there is no problem with the speakers. The problem could be with the software DVD player, or the audio setting on the DVD.

If I can be of further assistance, please let me know.

And, remember; always include the type of Operating System and the type of computer you own, when you submit your questions. It simply makes for much faster solutions.

Have a wonderful morning.

There are several reasons why there is no sound coming from the rear speakers.

• Improper connection of the signal cable is a possible reason why there is no sound coming from the rear speakers.

Green connector is for the front left and right channel. Black connector is for the rear left and right channel. Orange connector is for the LFE (Low Frequency Effects) subwoofer and the center channel.

The connectors for the Logitech products are color coded as explained. The connectors on the sound card may not be color coded or a different color coding maybe used depending on the manufacturer of the sound card. Check the manual for the sound card to make sure the correct connector is connected from the Logitech speaker to the sound card.
