Windows 7: Scrambled Noise At Higher Frequencies

No. The signals are different. Either you choose stereo, which will play anything, ( even "Mono" if no stereo channel is present) or you choose 5:1 which will only provide 5:1 surround sound if the signal is designed to do that.

Have you now solved all your issues with noise etc?

The issues with noise have indeed been resolved, thanks a lot Mike, you too neo.

All I wish to know is how to set the speaker to 'stereo' or any other setting that makes all my speakers play the same sound instead of just 2.

I tried:
- Control Panel
- Sound
- Configure Speakers
- Stereo -> next->next->finish

Did not work?

Thanks again, hoping that I can get some advise on this one aswell.

In order to play something in 5:1 surround sound, then the signal you are using has to have the 5:1 sound encoded. If It does not, then it will not play those channels, because they don't exist in the signal.

If you set your audio devices to stereo, they will use any stereo encoding, and ignore anything else. ( Simplified explanation).

It is possible to get all your speakers to play the same channels, ( with a bit of jiggery-pokery and external wiring), but it will sound awful. The only way such surround sound systems can work properly, is if the channels required are in the signal. If they are not, it wont work. The system decodes the signal and sends the correct channel to the correct speaker. If the channel does not exist, then nothing happens. Most music is only available in stereo. Trying to play it on a 5:1 surround sound system wont work.

5:1 surround sound ( and other variations), are only useful for film soundtracks etc, which support the necessary channels.

For more information;

Than it's a mystery, because my old computer played any sound on all 5 speakers.

And, if what you're saying is true, than the whole point of a surround set is quite useless,
I was already tempting to buy a 5.1(7.1) headset soon, but this is only making me want it more O_O.

.. Scary stuff, electronics.

5:1 surround sound is only of any use to signals that support it. You can connect any number of amplifiers and speakers to any output. This will give you sound in all the speakers, but it wont give you surround sound, just the same signal on all speakers.

I had a quick look for you and solution for

Stereo x2
Stereo x2
LFE .1

Right click Sound icon on your screen
> Playback devices
> right click on 'speakers' panel
go to 'properties'
tick 'speaker fill' in (menu heading) 'enhancements'

PS There is also something called 5.1 stereo "UPMIX" which converts a stereo source to quasi 5.1/7.1 (in either hardware or software)

Have a read about it!
Might need posher soundcard though which offers this!

I tried what you said,
It did enable all the speakers. Only the backspeakers are a bit low on volume + a little echo

I tried
>Right click on 'speakers' panel
> went to properties
> Tick 'Room Correction' in (meanu heading) 'enhancements'

It made a lot of beeping noises, trying to find the correct sound itself.
My front speakers' volume was lower and the back, was somewhat higher with a little bit of echo.

Can't wait for the headset

I apologise for the double post.

I wanted to thank both Mike Connor and neo101 for helping me figure out the sound problems.

Even though not all 5 speakers are working all the time, they atleast give the correct sound they should.
I will look for a proper headset, which will suit me best on some of the following terms;
- Comfort
- Amount of 'build in speakers'
- Quality
- Price

Anyhow, thanks guys !
