Hello arch community. This is my first post.. like the topic says.. a newbie post.
Well im going throw the question.
I have just installed arch.. and i want to configure my alsa.
First step: download it. Then just default configuration.
What happend then, i got this sound controller:
[ramiro@localhost ~]$ lspci | grep audio
00:0c.0 Multimedia audio controller: Creative Labs SB Audigy LS
The thing is that i have a Creative 7.1 subBuffer and i can not use all loudspeakers.
I just can use 4 of them and the buffer..
I have already read the ALSA wiki and ALSA configuration for 4.1,5.1,7.1 tutorial. I try to follow step by step but didn't work also.
I do not what to post about configuration. If /etc/asound or any alsa.conf of another dir. If some one of you could guide to me to see what the problem is, i will get appreciate to much .
I hope not to be annoying to us with this kind of question. But i'm just getting started at this beauty distribution .
Thanks!
Edit: I'm sory! i didn't know that i was posting on the Newbie Corner Forum. Please move it to the correspondent one.

Don't worry about your question place. You are on the corresponding one .
Firstly if your card is correctly recognized (if you hear anything form the speaker it is the case) you, normally, have nothing to configure in /etc/asound.conf etc.
ALSA is already created for you several devices to use depending your needs. You can see them with
aplay -L
command.
If you want to use all of 7.1 speakers you must choose something like surround71 for the output device in you player and your sound source should have 7.1 channels also.

Sorry, I can't see the images form imageshack here. Could you post it in text or on another fileshare? Just the output of aplay -L in terminal will be sufficient.

Ok. This is the list of all your sound devices. They are all attached to your soundcard.
These lines
surround71:CARD=CA0106,DEV=0
CA0106, CA0106
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
are about your 7.1 device.
Some players like VLC or Totem chooses the output device automatically. Usually they are limited to 5.1. To use 5.1 output you need to select this option in the configuration menu somewhere in sound or audio tab. But in my knowledge they are incapable to send 7.1 output.
In mplayer or xine you can specify the output device and the sound will be sent without transformation. So to hear all your 7.1 speakers you need to have 7.1 source (DVD for example) and a player capable to handle it.
To simplify your configuration you can make your 7.1 device default by adding
pcm.!default {
type plug
slave.pcm "surround71"
}
to /etc/asound.conf or .asoundrc (http://alsa.opensrc.org/index.php/FAQ026)

"default" is meant to be for 2 speakers, so I don't recommend messing with "default".
See my config and look at "pcm.upmix_20to51", assuming that you're trying to route 2-speaker output to more than 2 speakers.
