2nd Sound card wont load


I need to have 2 soundcards for mythtv(Since I have to tv capture cards).

I got the video capture for the cards working, but I cant seem to get the audio correct.

I have an onboard sound thta works and uses cmpci module.

The card is a vortex2 which I am using alsa drivers for and the au-8830.

Here is the kicker, both work, but only the first one which is in modules.conf works. So If I switch them in order, the vortex card works and the cmpci card doesnt.

Here is my modules.conf. Can anyone give me a hint here please.

alias parport_lowlevel parport_pc
alias eth0 tulip
alias eth1 tulip
alias eth2 8211
alias usb-controller usb-uhci
alias char-major-89 i2c-dev
options tulip options=3

alias char-major-116 snd
alias char-major-14 soundcore

#onboard audio
alias snd-card-0 cmpci
alias sound-slot-0 cmpci


#vortex2 card
alias snd-card-1 snd-au8830
alias sound-slot-1 snd-au8830
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss


alias char-major-195 nvidia

I'm not an ALSA expert, but your modules.conf looks kinda funky to me. I've had as many as three different cards working on a system, and I think your modules should look more like something like this:

***

alias char-major-116 snd
alias char-major-14 soundcore

# First card
alias snd-card-0 cmpci
alias sound-slot-0 cmpci
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# Second card
alias snd-card-1 snd-au8830
alias sound-slot-1 snd-au8830
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss

# Sound cards in system - your problem may be as simple as adding this.
options snd cards_limit=2

***

YMMV - I'm using completely different cards from you.

Good luck....

Just FYI- I fixed the problem. I ended up using ALSA drivers for both cards including the onboard sound. I had to compile alsa with the 2 cards in the config turned on. then alsaconf saw both cards.

I originally was using the ones Redhat installed when I first built the machine.

I still do not know why it didnt work with the old one, but I couldnt get it to work. If anyone knows maybe they can list it here.
