Surround sound problems

The broadcaster of the TV station has to tell you they are transmitting surround sound - sometimes they are just transmitting stereo. Also, the media as in CD's and DVD movies must have surround sound embedded or recorded on it to allow surround sound.

configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.
make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer.  connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.

LCD will display which speakers are active. And this depends on 2 things: the source signal and decoder mode.
If source signal is stereo, only front L+R speakers are used. For 5.1 signal (for example DVD over HDMI / optical/coax spdif) all speakers installed (which are not set to None) are used.
To listen to stereo input signal using all speakers, switch decoder to enhancer mode.

I think you mean the display only shows Front >>Channels<< available.

What source? Digital or analog (analog is only stereo).

Try selecting a surround sound mode, or 4ch stereo.

have you tried putting it in a different program mode?

Redbird,

What do you have in the "multi channel input" jacks on the rear of the receiver? Those inputs Right, Left, Center, Surround R+L, and Sub are used when selecting 6 channel mode. They bypass the receivers surround processor board.

all your speaker channels are working so your problem lies with a setup fault. when you watch tv you are only feeding a stereo signal into the amp. you need to select the internal surround sound generator. you need to select either the movie or surround function. the unit will convert the stereo signal to 5.1 channel surround.

I had the same problem. Set the reciever on 6 channel stereo. On this setting, you should be getting the same sound out of each speaker. Isolate which speakers aren't getting sound. Now, on your speaker switch (the A/B button), select A. If that doesn't fix it, select B. If that doesn't fix it, try A and B (if you can on your reciever).

Now, when you switch back to pro-logic, make sure your a/b channel switch is in the position that worked in 6 channel stereo. Yamaha recievers have a memory, and when you switch various modes, it makes auto adjustments based on what you had set in the past.

Hope this helps

don't switch to stereo mode. switch to prologic mode
