I just recently picked up some Logitech x530 speakers set, my friends recremindation. Everything works fine on my windows box, on linux however. Sound is only outputted to the right and left speaker. Skipping all the other speakers completely. No sound is outputting from them at all. I tried to follow a few tuts on surround sound with alsa, they either just didn't work, or caused soudnt o no be outputted at all. Any solutions?

If you are playing a stereo track (2 ch) and you want to hear from all your 6 speakers, follow this guide:
http://alsa.opensrc.org/index.php/Playi … up_(Howto)
If you have a real 6ch track (from a DVD, for instance), just use the right output plugin with your preferred player: xine-based program can usually be configured to play automaticaly those kind of tracks using surround51, mplayer has a bunch of commandline switches like:
mplayer -ao alsa:device=surround51 -channels 6 dvd://1

I did follow that guide before this post, still a no go. As for the movie part, I already got that working.

the following is my ~./asoundrc.
I use ch40dup as default device and - for instance - amarok plays a stereo track using both front and rear speakers of my 5.1 setup.
Try editing the following according to your need and to your souncard model (mine is an Audigy).
pcm.Audigy {
type hw
card 0
}
ctl.Audigy {
type hw
card 0
}
ctl.mixer {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm ch40dup
}
pcm.ch40dup {
type route
slave.pcm surround40
slave.channels 4
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
pcm.ch51dup {
type route
slave.pcm surround51
slave.channels 6

ttable.0.4 0.5
ttable.1.4 0.5

}
