6 ch sound
 

I have 5.1-ch speakers and nForce2 6 chanel sound card. If someone can tell me way when I play the movie all speakers doesn't work only front and rear work fine.

With AC3filter (http://forum.bsplayer.org/viewtopic.php?p=15637#15637) you can set up output type (look at Main and Mixer tab in AC3filter's properties) - in your case 5.1 channel.

Except the ac3 problem it can be because of your sound card setup. Do you normaly hear voices :shock: with all speakers, or do you always have that problem?
