I recently upgraded to Windows 7 and this machine here:

Which claims to have 5.1 channel HDA. When I plug my logitech speakers in I only get the front speakers working.

I have the settings correct in Windows and the speakers definitely work.

Please advise ...

Are you all playing content compatible with 5.1? for example a 5.1 movie or tv show. Music is only stereo. This means that if you do not have software that emulates a 5.1, you always hear the front speakers.

Por otro lado, ¿qué programa estás usando? VLC, Media player home classic, etc...

How are you connecting the speaker system and which audio card are you using for EAX?

See example here

You should look in the configuration menu of your audio device (proberly a realtek device, red sound icon). There look for the tab 'speakers' and if I am right it should say stereo there, change it to 5.1 surround.

Good luck ;)

When I go to 'Realtek HD Audio Manager' I have the settings as 5.1 and it tests each one individually and that works.

When I go to play a video or some music I only get the front speakers.

So 5.1 works perhaps the media I am playing is not actually compatible as @Crower suggests? I'm sure my previous machine played EVERYTHING in 5.1 ... is there something I am missing for Windows 7 - perhaps a codec or something?

Go to the control panel then open the realtek HD audio Manger, make sure you are on the speakers tab below that the speaker configuration tab and put a check next to speaker fill this will playback stereo sound on all surround speakers.

is possible that your previous machine had an emulation system. For example, my 5.1 system has a button that turns the audo stereo to 5.1. called matrix

Also ... when I do turn on the speaker fill option the rear speakers are really faint, can barely hear them?

Now, I know the speakers work fine, but there is something not quite right here?

Go to the room correction tab and adjust the dB to make the rears louder.
