Help need help setting up surround sound

Hi Our stereo was broken so we sent it for repair. When it was brought back to us it was just dumped on our sitting room floor and not set up for us. The problem is that we are having difficulty in setting up the speakers as we have misplaced the manual. There is too much bass coming through the middle speaker and not enough bass coming from the sub woofers. Please can anyone out there help us????? Sonia

I have a panasonic tv and i need to know how to hook up home theather system lenoxx electronics model HT 3915

Hi, the Panasonic t.v. more than likely has more than one kind of output. One of them should be actually lit up with a red glow around the edges, that is the fiber optic digital sound output. It's called a" TOSLINK" connector and is plugged into a matching jack on the surround sounds rear panel. The t.v. may also have a "LINE OUT", " T.V. AUDIO OUT " or " FIXED AUDIO " output this may be in the form of a small 3.5mm stereo headphone jack ( i still call them 1/8 in. plugs) this you can plug into the surround sounds line input on the back panel. If the line input on back of the theater system is rca just use a stereo headphone plug to rca adapter. I hope this helped and thanks for choosing FixYa, good luck-Prodzilla

I have an older model Yamaha HTR 5830 receiver and I want to set it up for surround sound (5.1). When I test the receiver all five speakers give back a signal, but nothing ever comes out of the center or...

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.

Trying to get surround sound speakers to work with TV

They come with 3 x 3.5mm stereo to 2 x RCA phono cables, so are obviously meant for plugging in to the back of a PC with 6ch output.

BTW - they're ****.

I have connected my new surround sound to the dvd player as everything else runs through it. Also found that it has a seperate switch for 5.1 surround sound (all the speakers active) and ordinary stereo. I'm unfamiliar with yours, but check for this switch, mine was hidden on the back of the base speaker.

Hope this helps

Only sound from Direct and Stereo settings on Denon AVR 788

Other listening modes (dolby, dts, neo6) are decoded from digital signals.

Direct will relay your only your discrete analog inputs - so if you want to use your AVR as an amplifier for those channels, you'll need to supply an input signal in a different manner.

Sound problem


I have a creative SoundBlaster LIVE! 24 Bit External Sound Card and this annoyed me for weeks.

depending on your surround sound reciever depends on the solution.

i have an Acoustic Solutions surround sound system with coxial and optical inputs, aswell as stereo red & white jack inputs.

not knowing the method or connection your using makes it difficult to give you a single solution so i'll list a few.

The soundblaster software shoudl include the Creative Audio console with all sorts of effects, one is CMSS (CMSS-3D) Stereo widening which is still stereo but gives a surround sound effect.. but i'm guessing you payed for 5.1 and you want 5.1 onto the next part

5.1 surround sound can only be produced when the actuall audio your playing contains 5 channels of audio, for example you cant play a stereo song in 5.1 surround sound without some sort of hardware or software sound manipulation. Luckily my surround sound system has Pro Logic II built in and some other effects which convert a 2.1 signal to a 5.1 signal and it works brilliantly. I'm not sure of a software alternative.

setup for your soundcard will be different under XP and Vista also, but there should be a properties option for your sound device where you can select your speaker setup such as headphones, built in speakers, 2.1 speakers, 5.1 speakers, 7.1 speakers and you should be able to manage this from the creative software.

If using Coxial / Optical or SPDIF under vista you MUST set the playback device as SPDIF, at least you have to with my sound card and drivers and seems to be a limitation of the actual sound card drivers for vista.

Personally i was looking forward to hearing the windows login melody in 5.1 surround sound too, but this doesnt happen.

Infact i find that almost all programs bar a few will not play Dolby Digital or DTS 5.1 surround sound via any or my output options hence the next solution..

if you have the 5.1 sound but winamp simply just plays it in stereo try the following.

You need to use DirectSound Output:

Preferences (Ctrl-P) > Plug-ins > Output > Select "DirectSound Output"

That should work in most cases, but if not, then:

Checkmark: "Allow hardware acceleration" in DirectSound Output config,
and make sure your sound card/chip is selected as Output Device.

Note that any changes will take effect only after playback is restarted.
In some cases, a Winamp restart is required.

If that doesn't work make sure you have the latest version of DirectX
(v8.x or higher is required)

Winamp 5.25/5.3 and higher:
For actual multi-channel files (ie. aac/wav/ac3/ogg/wma files encoded in 5.1ch surround, as opposed to standard 2-channel stereo mp3's), you need to checkmark "Allow surround sound" in 'Winamp > Prefs > Playback' for the music to play in its original 5.1 channel format (Note that this setting is checkmarked by default).

Windows Vista:
In addition to the above instructions, Vista users will also need to go to:
Control Panel > Sound > Playback tab > Speakers > Configure:
Select: 5.1/7.1 Surround.
Control Panel > Sound > Playback tab > Speakers > Properties > Enhancements tab
and checkmark "Speaker Fill"

Hope this helps

No sound when using dish or regular tv

This may be old news but just in case ...

Typically you need to consider the surround system as the central point for sound distribution (and in newer receivers, the distribution point for video signal as well). So you need to think of your TV and Satellite as sound sources and connect them to the IN side of your surround sound system. From the back of your TV then, look for the Audio OUT (commonly Red for right and White (or black) for Left. Connect these to the IN on the back of the surround system. Likewise for your satellite box. Then make sure you select the appropriate source on the surround system. If the system supports the video signal, you can route that as well. Beware that you'll need some sort of simulation (provided by the Phillips unit) to upconvert stereo to surround ... check the manual online. If you post model numbers for the Phillips and satellite units, we might be able to direct you more specifically (provided we can find manuals online)

Polk Audio RC55i In-Wall Surround Speakers (can't hear whispers)

I'd make sure that the receiver surround mode is set for one of the digital settings, such as Dolby Digital or DTS, and make sure that you have the center channel level adjusted to a level similar to the other two front channel speakers. I've seen/heard this happening when using dolby digital material & having surround set on something like 'hall' or 'stadium' or dolby surround, where only 4 channels are used & the amp has to 'mix' sounds to the left & right front speakers. It'll often sound like the actors on screen are talking out of the bottom of a barrel, with a hollow & tinny character to the voices.
