Getting two sound cards to work with ALSA
OK, I could not find much useful info through searching the forums, and the Alsa docs aren't helpin much either.

I use an M Audio Delta 44 sound card for doing recording on my Gentoo machine. Recently I bought an SBLive card so that I could just have a simple card to play music out of and connect to my headphones. My plan is to set up the SBLive card to be the main one, and use the M Audio card for working with Ardour and Jack.

I haven't been able to get this to work however; though the SBLive comes up when I run lspci | grep audio, Alsa won't recognize it. Here's the output or lspci | grep audio:


0000:00:09.0 Multimedia audio controller: Creative Labs SB Audigy LS
0000:02:04.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 [Envy24] PCI Multi-Channel I/O Controller (rev 02)

When I try to run alsaconf, only the Delta 44 (ice1712) shows up. (I know alsaconf will only configure one card, but it seems to me like the SBLive should show up.) I have the following lines added in my /etc/modules.autoload.d/kernel-2.6:



Here is my /etc/modules.d/alsa:

Here is my .asoundrc:

ctl.emu10k1 {
  type hw
  card 0

pcm.ice1712 {
  type hw
  card 1

ctl.ice1712 {
  type hw
  card 1

I am using alsa version 1.0.9, and am using it as modules, rather than compiled into the kernel. Only the ice1712 card (Delta 44) is being recognized.

Thanks for any insight.

Despite your configuration, it doesn't seem the module for the SB Live is loaded. Can you post the output of lsmod?

Ahg, sory about that. Here's the output of lsmod:

I had heard that the emu10k1 was the correct driver for the SBLive cards. I just checked the Alsa matrix, though, and it lists the driver for the SB Audigy LS as the ca0106 driver. I tried loading this in, yet got a module not found error. Is this driver listed for some other card in the kernel config?

FreeThinkerJim 08-24-2005 09:25 PM

I just looked at my kernel config stuff, and I found the entry for the SB live in the menu, and sure enough, its the ca0106 driver that's the right one, and not emu10k1. The reason that ca0106 doesn't load is probably because it wasn't compiled with your kernel. The right option for your card's driver can be found in Device Drivers-> Sound-> Advanced Linux Sound Architecture -> PCI Devices -> SB Audigy LS / Live 24bit when you run make menuconfig. Be sure to compile it as a module.
