Re: [Alsa-user] Trouble setting up two sound cards in same box

Thanks for the help. Unfortunately, it's still not working. I made the changes you suggested, but when I do the modprobe I get:

/lib/modules/2.4.21-xfs/alsa/snd-cmipci.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg /lib/modules/2.4.21-xfs/alsa/snd-cmipci.o: insmod /lib/modules/2.4.21-xfs/alsa/snd-cmipci.o failed /lib/modules/2.4.21-xfs/alsa/snd-cmipci.o: insmod snd-card-1 failed

and the last entry in dmesg is:

C-Media PCI soundcard not found or device busy

I just noticed that my USB controller and the C-media pci card are both using IRQ12:

00:02.2 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 07) (prog-if 10 [OHCI]) Subsystem: Silicon Integrated Systems [SiS] USB 1.0 Controller Flags: bus master, medium devsel, latency 64, IRQ 12 Memory at cfffe000 (32-bit, non-prefetchable) [size=4K]

00:0f.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)
        Subsystem: C-Media Electronics Inc CMI8738/C3DX PCI Audio Device
        Flags: bus master, medium devsel, latency 64, IRQ 12
        I/O ports at b800 [size=256]
        Capabilities: [c0] Power Management version 2

Should they be able to 'share' the same IRQ? Any ideas?

Thanks again

cards_limit=2 is OK.

The parameter wouldn't be "snd_enable" but "enable=1", but this is the
default anyway.

Use "options snd-cmipci index=1".

Does "modprobe snd-card-1" load it?  If yes, then one of your startup
scripts is still configured to load only the first card.
