I've been fiddling with this thing for hours now and can't get it to run any other speakers besides the ones connected to the, front left, front right, front left B, and front right B speakers. The subwoofer, center, and any surround speakers don't come on. I'm sure there's a simple button to press or setting to change to get it off of L+R and let it play all of them, but if I'm mistaken, help me out.
Image


The receiver is a Yamaha HTR-5740.

All the speakers are fine, as they all work flawlessly with my other Yamaha HTR receiver.

Here's some pictures of the front if you can spot a button that might help me... :swearing: There's not many other buttons on the remote, but if the remote is usually used to do things like this tell me.

This is so frustrating...
Image


Note in the last picture... starting from the left speaker ports, the first 8 are the only ones that work. The other 8 which consist of center, and surround don't get sound. Also, I have the Polk Audio PSW250, and it's connected via the yellow cable, as the port is called "Subwoofer"..
Image
and it was very similar to the other HTR Receiver I have which is a similar model.

And yes, I know the colors aren't correctly matched on the grey cable. It's been like that ever since I bought the cable and has always worked flawlessly in the past. The red cable that splits from the grey doesen't function, but if I exchange it with the yellow it's fine.

are you feeding your receiver multi-channel input? What is the source?

If you are and the receiver isn't decoding properly, try resetting it. You'll need to look in the manual for instructions on how to do this.

Do you have both speakers "A" and "B" selected? Maybe turning one set of them off will help. In the second picture under "vcr" it says "sp" then underneath that it shows AB. That could be that both are selected.

Then as soloz suggested, do you have a multi-channel input and is the receiver set to mult-channel?

Sorry for my noobiness

, when you say "feeding your receiver multi-channel input, and what is the source" what do you mean? There are multi-channel inputs on the back, and I've tried to plug the audio cables in there but the sound has always come out slightly fuzzy and low-quality.

If I turn the A off, the right speaker A and right speaker B turn off, same concept with the B switch. Turning one of them off doesen't make a difference.

As for multi-channel, I believe that would be the option I've been looking for, although I can't quite find out where it is.
Image


Thanks for the replies, it's appreciated.

Here's two more pictures of the "Multi channel inputs" and where the speakers are connected currently.

They've always worked fine in the past with that combination.

If you wanted to do a multi-channel you would need 3 different RCA to mini-jack connectors, also your sound card would have to support 6 channel output.

Hmm.. now I'm even more confused.

The grey cable that I've always used to get audio from the pc is the red+white+yellow cable, and it turns into a single 3.5 jack that fits in a earbud/headphone plug. I usually go to the back of the pc and plug it into the green plug and that's how I get sound. Then the yellow+white (red doesen't work) go into the red and white audio plugs on the back of the receiver, and then I select whichever input that is, and it's all done. This is a new (not technology wise) receiver that I've never used before and it's the first time I've run into the problem.

You are only getting left+right audio because that's all the input the receiver is getting.
use optical or coax as a signal source and set your PC to output 7.1 or 5.1... whatever you're trying to setup.

You need to hook up the speakers better...
I see far too much copper there, you'll cause a short.
ONE wire per terminal.

IF you dont have any way to actually get surround channels to the receiver (coax or optical) and you just want all of your speakers to output in ghetto fashion, press the program button a bunch of times. you should have two or three "STEREO" options.
Regular stereo
direct stereo
and 7ch stereo (or 6 or 5 dependong on the receiver)

Image


make sure your front (main) speakers are only plugged in to the front L+R "A" channel.
TURN OFF THE B CHANNEL
Image


If you manage to run with a digital signal (Coaxial or optical/spdif) you can confirm you how many channels of audio you are receiving from the computer by looking at the front panel, bottom right corner. Right under the volume level
right now it shows L and R meaning you're only getting a two channel signal
it should show like this when it's getting a proper signal
Image


EDIT:
I looked up your sig-rig's motherboard.
you do not have any kind of multi channel or digital audio output.
I suggest, if you are willing, that you get a cheap sound card with COAX or Optical audio output. those will be a no-fuss hook up. just a single cable and it will give you proper multi-channel output. Optical is better in my opinion, because information is sent via light-waves so electromagnetic interference is nothing to worry about.

you can order a cable from a place like Monoprice.com for MUCH cheaper than what best-buy will offer. Though walmart or target may have a more economical solution.

Woah, okay.
Image


Right now I'm using a temporary pc, so I just want the speakers to all work, "Ghetto way"
Image
.

I switched it to 6ch Stereo, but that doesen't change anything, the center, surround and subwoofer still don't come on. If I missed something, shouldn't the subwoofer come on even with just L+R channels?

As to your statement about too much copper, what's the correct way to connect speakers to the (terminals?).
Image


Thanks. +Rep given to all.

Edit: Right now I would really just like to get the subwoofer working, I won't have this pc for that much longer so if it's just the sucky motherboard that's giving me all this trouble, I can live wtihout the surround and center for now. Is the subwoofer not working for the same reason the surround and center aren't?

Grab the remote.
Go in to setup.
manual setup
speaker/audio options
in here you should be able to select speaker sizes and enable them.

my guess is currently the unit doesnt think you actually have other speakers.

you have to tell it you are using Front/Center/Surround/Sub

I suggest setting all speakers to "small", and setting the crossover (if such option exists for you) around 80hz. there should be a BASS OUTPUT option. it will have three settings
FRONT
SUBWOOFER
BOTH

select SUBWOOFER.

now everything below 80hz will be sent to subwoofer, and all the other speakers should play the rest.

good luck!

p.s. If it doesnt work, there's something wrong with the unit or i'm missing something

you only are feeding your receiver 2 channels of audio. If you want all the speakers to play you would have to configure your receiver to matrix the sound to the other speakers, or change the input method to something that can carry more than 2 channels.

This worked.
I used the remote to enter basic setup and changed it to 6 speakers, and turned the subwoofer to on. Didn't mess with the crossover because I'm so happy they're working for now.

To avoid having this problem, can someone link me to a nice cable that would work fine in the future?

Thanks for everyone who's helped.

And +Rep to soloz2.

Just make sure the stripped wire is inserted all the way into the terminal, and the nut tightened down. The hole in the end is for banana plugs, not to just cram wire in to (though, everybody's done it at some point or another, especially when troubleshooting)

You dont want extra copper showing all over the place as it will increase the chances of shorting it out, especially is it's one of the (+ / RED) connections which can damage the amplifier.

also, make sure your wires are oriented properly. What's positive/red at the amp is going in to the positive of the speaker terminals. alot of people think it doesnt matter, but if you wire speakers out of phase you'll get a pretty funky sound stage. Speaker wire is typically lables with + + + + + + + on a wire, or a stripe, or writing
SOMETHING to differentiate between wires.

good luck!

not to try and confuse you but optical and coax both only have the bandwith for a 2ch single so the option to output 5.1/7.1 on your soundcard will be unavailable. you need HDMI for your sound card to output in true 7.1.
with the optical cable the receiver will still have to decode a 2ch single and 'try' to decide what audio should go to what channels. this will still work fine but it might or might not be worth upgrading the audio cable.

Are you saying that PC soundcards only output 2ch via optical/coax?
because both media forms are very capable of transfering all channels of audio...

EDIT:
did some searching.
Looks like you're right.

For games and such, only PCM 2 channel audio will be transmitted via the digital media. DVD's and such will, however, be capable of transmitting Dolby surround or DTS, but they send the compressed audio, which is then decoded by the receiver. Makes sense.

HDMI is the only way to transmis uncompressed multi-channel PCM
