ALSA problem

[ArtoH]

Hi all,

I have a weird problem with ALSA sound. I got an error "Invalid module format" when I try to load alsa modules. There is first listing of my setup and then some debug information.

- MOBO Asus p5w
- processor Intel P4 prescott 531 3GHz
- kernle 2.6.18-r4 (gentoo), compiled with gcc 4.1.1
- gcc version 4.1.1

Here is lscpi listing:

Ok and then the actual problem:
When I try to load alsa module I got a lot of Warming messages

/etc/init.d/alsasound start

And here is my dmesg output:

Ok and here is what I have tried to do.

1. Removerd alsa-driver, recompiled kernel and reinstalled alsa-driver
2. cheked that emerge uses the same gcc version than kernel was compiled (gcc 4.1.1)
3. Rebuild library dependencies using revdep-rebuild
4. reemerged system, recompailed kernel and reemerged alsa-driver

I'm running out of my knowledge and don't know what to do next.

You have the modules for *both* in-kernel and alsa-driver compiled and installed in /lib/modules/`uname -r`.
Remove that directory, rebuild the kernel *without* ALSA support in-kernel, do make modules_install, and ten install alsa-driver, reboot and it will work.

That one worked
Thanks a lot!

Good to keep in mind for next time...
