[linux-audio-user] How to turn 5.1 on ALC655?

Hi there. I have a little problem with my soundcard. It's onboard Realtek ALC655 AC97 codec Chip on Gigabyte GA-7VT600 1394 (more infos on http://www.gigabyte.pl/MotherBoard/Products/Products_Spec_GA-7VT600% 201394.htm) and I'm using Mandrakelinux 10.1 (Official) with kernel 2.6.12.3, KDE 3.4.1 (with arts) and ALSA 1.0.10 + Soundblaster 1024 Player (aka SB Live! Value [CT4832]) and I have two questions: 1). how to turn on 5.1 surround sound system in ALC655 ? I've found one site about it (http://alsa.opensrc.org/Alsa) and I've tried to do this... but it doesn't work. 2). and how to (is it possible anyway?) to use both sndcards simultaneously as one card? I want to use ALC655 as a 5.1 sndcard and my SB as 4 speakers (2 speakers + headphones) and mic-in. I know it sounds crazy, but if someone can help me I'll be grateful :) Thanks, I hope someone can help me :)
