Soundcard
 

I just compiled a new kernel and my soundcard isn't working. I compiled the kernel with sound support and included the module I know works with my soundcard (worked with my previous kernel)
Soundcard: Soundblaster Audigy
(new)kernel: 2.4.22
distro: slackware

when I type: modprobe emu10k1
I get: /lib/modules/2.4.22TestKernel2.4.22/kernel/drivers/sound/emu10k1/emu10k1.o: init_module: No such device
/lib/modules/2.4.22TestKernel2.4.22/kernel/drivers/sound/emu10k1/emu10k1.o: 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/2.4.22TestKernel2.4.22/kernel/drivers/sound/emu10k1/emu10k1.o: insmod /lib/modules/2.4.22TestKernel2.4.22/kernel/drivers/sound/emu10k1/emu10k1.o failed

when I view /proc/pci I see that my soundcard doesn't have a IRQ
# /proc/pci: Bus 2, device 10, function 0:
Multimedia audio controller: Creative Labs SB Audigy (rev 3).
Master Capable. Latency=32. Min Gnt=2.Max Lat=20.
I/O at 0xd400 [0xd41f].
(just copied the soundcard info)

and I found this in dmesg:
PCI: No IRQ known for interrupt pin A of device 02:0a.0. Probably buggy MP table.
EMU10K1/Audigy soundcard not found or device busy

I'm lost on what to do now.
Thanks.

From the beginning it looks like something is very wrong. cd into the directory where the driver 'doesn't' exist:
cd /lib/modules/2.4.22TestKernel2.4.22/kernel/drivers/sound/

Poke around and see if you find it, if you do..

insmod using the full path.

Run:
depmod -ae

And also, that's not a normal lsmod, I'm thinking you typed lspci, and either meant to say that's lspci, or didn't post the correct data ;)

Lastly, not completely related, but have you looked into using ALSA for that soundcard instead of the kernel driver?

Cool

your right, thats supposed to say lspci.

I found the driver:
/lib/modules/2.4.22TestKernel2.4.22/kernel/drivers/sound/emu10k1
so I cd to that directory and type:
insmod emu10k1.o

I get:
emu10k1.o: init_module: No such device
emu10k1.o: 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

I didn't get anything from depmod.

I'm fairly new at linux, but it seems to me that my Soundcard isn't being detected. It shows up in lspci, but it has no IRQ (looking in /proc/interrupts and /proc/pci, it doesn't have an IRQ)

yes, I have checked in to ALSA as well. I've installed ALSA for my soundcard and I get similar problems when trying to load the modules.(actually I get the exact same error as above)

The IRQ part really confuses me. Why wouldn't my soundcard be assigned an IRQ?

Thanks

I just did a kernel upgrade to 2.6 test3, and I think I remember having to compile in Plug and Pray support. Is it possible that you left this option out and that is maybe why no IRQ is assigned? Did you keep your .config file from your kernel compile? I would love to see a copy so that we can diagnose your compile options... the answer may be there.

You want me to post the whole .config file? or just certain parts?

Its a rather large file to be posted, isn't it? (899 lines)
:)

Yeah, it is a bit big..... :P

specifically, if you could try to single out the sections re: sound card config/PCI and any plug and play settings.

This may not be the culprit, but I think it is best to rule this out before we start grasping at straws....

If you want to e-mail the file to me, I'd be happy to give it a go.
