The reason you are not getting center is because the sound source needs to have multiple channels recorded. Almost all the music today is stereo, so you would not be able to play on all 5 speakers or surround sound. I think your speakers that you have is detecting stereo only so it sent the sound to four channels and it also mixed the two channels for the subwoofer. To make sure your setup can play 5.1. Download speaker-test from the ALSA wiki site. If all channels works, run mplayer but in the command line add "-channels 6 -ao alsa1x:surround51". Next play a DVD movie or an AVI movie with AC-3 audio. You should be able to hear in 5.1 surround sound. Though in the movie, try to pick a scene where a lot is going on. If mplayer complains that it cannot find surround51. At the console type "aplay -L". You should see a whole list of entries you can use. Usually surround51 should be in the list.

Not all motherboard manufactures programs the sound chip the same, so the ALSA module may not work well in 5.1 set ups. You may have to use digital output or get a real sound card.

I have surround51 in aplay -L. I ran the speaker-test program, and something odd happened. To speaker-test, the test was successful. But I heard the Front Left and Center speakers were the same, i.e., when it played center, the sound came out of front left. Its not just music that I try, its some games, too, like Max Payne 2 or Warcraft3.

EDIT: How would I enable digital output? Alsamixer doesnt have an digital output options in it. Maybe theres a way to put options in alsamixer?

That's a good point ( and the first good point I have read from Electro at that). . .

Some on-board sound chips don't down mix 2 channel audio playback into 5.1 channel sound.

My on-board sound does this in fact. But I use an Audigy now... god I love that card.

You should consider getting a "real" sound card. The difference in sound quality is amazing.

Do your speakers support digital input? if not you are wasting your time thinking about it.

Thanks for the input guys. I think Ill just order an SB Live! and get some real sound quality (although there isnt an option to disable onboard sound in the BIOS...).

Get Turtle Beach Santa Cruz. It has a lot better sound quality than Creative Soundblaster LIVE and Audigy. It does not color the sound like Creative Labs cards do. I have a Turtle Beach Santa Cruz. The sound is a lot better.

Look in your motherboard manual for a jumper setting.

The Audigy is a much better investment then the LIVE 5.1.

It is fully supported under linux and sounds great.

Turtle Beach Santa Cruz is over priced. . . you can pick up an OEM Audigy for under 60 bucks Canadian. And IMO they sound almost the same (to me the Audigy sounded better and adds firewire to your system)

The Santa Cruz is not over priced. I payed about $43 for it at newegg. In LINUX, there is no support for 96 KHz sampling rate, 24-bit resolution, and EAX. Creative Labs sound cards killed several of my systems by corrupting data. Search this forum, you will found out that people said that the Santa Cruz is much better than Audigy 2.

I guess people are too brain washed over the years when Soundblaster LIVE! came out.

Have a look at http://www.pcavtech.com/soundcards/compare/index.htm
