Here's the situation. I am currently running KnoppMyth (a Knoppix based distro of Mythtv). I have the system running fine with one bttv card (an ATI TV Wonder VE) and the onboard sound (Sis chipset). I decided I wanted another tv tuner so I bought another bttv card (AITech Wave). Because both of my bttv cards do not have btaudio, I am forced to have a sound card dedicated for each card. I decided to add a Cmedia pci card, and have been having troubles ever since. Thus this message. At the moment, the onboard sound works fine, but I'm not getting anything from the pci card I added.
Here is what I get when I do an 'lspci -v' in regards to the sound cards:
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0)
Subsystem: C-Media Electronics Inc: Unknown device 0300
Flags: bus master, medium devsel, latency 64, IRQ 10
I/O ports at dc00 [size=256]
I/O ports at d800 [size=64]

I/O ports at b800 [size=256]

Before I installed the pci card, I did an '/etc/init.d/alsa-config' to get the settings for my onboard sound. Here is what was generated in /etc/modutils/alsa-0.9-knoppix :
# --- BEGIN: Generated by ALSACONF, do not edit. ---

# --- END: Generated by ALSACONF, do not edit. ---
I then disabled onboard sound in the bios and installed the pci card and ran alsa-config again to get the settings for the pci card:
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 0.9.0-knoppix ---

# --- END: Generated by ALSACONF, do not edit. ---
Although the file said not to edit it, I did it anyway :D .. I found this page that kind of explained what need to be done to get both cards working:
Here is my combined /etc/modutils/alsa-0.9-knoppix :
# Start

alias char-major-14 soundcore

options snd-intel8x0 index=0 snd_enable
#Set Card 1 (Cmedia)
alias snd-card-1 snd-cmipci
options snd-cmipci snd_enable
#END
After booting with these settings, lsmod doesn't show the cmedia's module (cmipci) as being loaded.

I am trying to get the onboard sound to be configured as /dev/dsp0 and the cmedia pci card as /dev/dsp1 . The cmedia pci card was pulled from another working knoppix box, and the new bttv card is outputting sound on it's line out.
Any ideas? Sorry for the lengthy message, but I wanted to try to answer as many questions ahead of time. I'm fairly new to linux admin, so perhaps my problem is basic. Your help is definitely appreciated!
