thnks and sorry for my english

I don't know if this is going to fix it but let's give it a shot. Go to a terminal and run:
Set the volume of every speaker as you please then press ESC.
Back in the terminal run:
Reboot and see if it works. The reboot is not needed but I suggest it always.

It does not fixed my problem

you need to be playing 5.1 media to hear sound from all 6 speakers. Some audio drivers on windows will automatically "upmix" stereo to 5.1, so that you get sound from all speakers. Conclusion, you hear nothing from the rear speakers because there is nothing there.

One solution is to "duplicate" channels, so that your front channels would be copied to the rear. You can do this by editing your ~/.asoundrc file. More details at alsa-project.org.

Also, you could try configuring your media player to use all 6 channels. For example, try using mplayer's surround filter:

It would help if you specify the distro and version you have.

If you have the gnome desktop, try bringing up the sound preference dialog ( System > Preference > [Hardware >] Sound ). Click on the hardware tab and make sure you have Profile set to 5.1. On newer desktops, to the right of the Profile selector, there is a Test Speakers button where you can individually test each channel. Make sure you try them several times. I have found that some profiles take a click or two before the test signal gets through.

I have Fedora 14 KDE
I have installed pulseaudio and allmost all ALSA plugins
