Question about Sony HT-DDW750 System

Sound from all speakers problem

I have hooked up the surround per instructions. I verified + and - are hooked up right. I ran the test tone feature, and sound comes from all speakers in the correct manner. DVD sound plays fine. However, when playing regular TV, sound only comes from the left speaker. No sound can be heard from an other speaker. This includes the subwoofer. I am at a total loss as to figure out what is causing this. Sound will not work from all speakers when not in PLII mode. Please help

I would suspect the lead from your tv or video and swap this.ie where are you feeding tv signal to amp from.more than likely faulty lead or socket at this point.swap around the leads and see does fault transfer to the opposite channel.keep with it sounds like set up problem of some sort,.

Why does sound turn off.


Follow these steps to troubleshoot if there is no sound or intermittent sound from the speakers.
IMPORTANT: Not all of these features and/or functions are available on all products. Consult the instruction manual that came supplied with your unit to verify if your particular unit has these features, or if more detailed information is required to perform any of the steps below.
NOTES: Click on the appropriate link below if the issue is occurring with a particular device or connection.
  1. Make sure the MUTE function has not been activated.
  2. Try turning up the volume level.
  3. Check that there are no headphones connected.
  4. Try setting the Audio/Video (A/V) receiver to a different Surround Sound mode.IMPORTANT: Verify that the source you are playing is encoded with Surround Sound audio. If not, the audio will be very difficult to hear using a Surround Sound setting. Set Surround Sound to OFF when playing a source that is not encoded with a Surround Sound signal.
  5. Check each speaker to make sure they are properly connected to the A/V receiver.
  6. Perform a Test Tone function to verify if the speakers are working correctly.
  7. Verify all external audio sources are securely connected to the appropriate inputs on the A/V receiver. NOTE: If the audio is being sent from a television to the A/V receiver, then it may be necessary to disable the internal speakers of the TV or set the audio output of the TV to FIXED or VARIABLE. If the audio output of the TV is set to VARIABLE, then you will need to increase the volume level of the TV.
  8. Make sure the correct audio input is selected on the A/V receiver.
  9. Confirm what type of HDMI® devices are connected to the A/V receiver and then check the following:

    1. Test each one of the HDMI inputs on the A/V receiver to confirm that all of the inputs for the A/V receiver are working.
    2. Try a couple of different HDMI cables to verify there is not a bad set of cables.
    3. Unplug the video source from the A/V receiver and connect the source directly to the television. If there is still a problem with the audio, continue to the next step. If connecting the source to the TV corrects the sound issue, service will be needed on the A/V receiver. NOTE: Additional troubleshooting steps are available to troubleshoot instances when the audio, video, or both goes out when using an HDMI connection.
  10. Verify the DEMO (demonstration) mode is not active.
  11. Change the ATT (attenuate) setting. NOTE: The procedure to change the ATT feature varies by model.
  12. Reset the A/V receiver back to factory specifications.
The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required.

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?


Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

No surround sound


Since it is new and just purchased, you really should return it for a new one. If you have connected all the speakers right, which you have since the test tone plays in all of them, there is a problem with the receiver. Don't wait too long or they may insist that yu take it for repair. You usually only have a short ime after the purchase to get an exchange. Some are 7 days and others are as much as 30 days. But it does need to be repaired, it is not the way you set it up.

I need help with my surround sound!!


The calibration mic thing is to balance the sound evenly on surround sound systems, it replacles the older systems "TEST TONE" speaker setup, in other words it will balance each speaker say in a 5.1 setup to adjust the level output so the listening position is not overwhemled by say the rear surround speaker overriding the front left & right speaker or the most critical the center speaker. The calibration mic uses computer tech to make it easier for the user, no sound pressure calibration is needed as with the test tone setup mentioned earlier. The wireless speaker situation could be possibly waiting for the calibration confirmation, Read any user manual information if available.

No sound from my speakers


Check your Surround Settings (Make sure you are in Full surround and not 2 ch) as well as your Input Source Remember the Surround Speakers will not give you a Full Audio Output it will only give you "background noise"

Cant connect rear speakers


Hey there Subaquakid, the nature of surround systems is to identify separate extra channels of information and send them to the right address, being the selected speaker. In order for the rear speakers to work they need to be sent a signal. The media which you are using may not have the rear channel encoded. therefore the rear speakers have nothing to announce. Please ensure your source cd has the suround feature encoded. Hope this helps. Good Luck!
