Long story short... I'm recompiling the snd_hda_intel module to enable CONFIG_SND_HDA_RECONFIG. This will allow me to reset the pins on the card to get my sound working. (This option is already set in arch and ubuntu - where I can reprogram my pins and get sound working).
I followed the 2 CentOS wikis pertaining to getting the full kernel sources and compiling a module... all seemed to go perfect. Unfortunately, when I try to load the new snd_hda_intel.ko module, I get the following:
FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.32-431.11.2.el6.x86_64/extra/snd-hda-intel.ko): Invalid module format
A little googling suggested I run 'file' on the two modules and here is the output:
/lib/modules/2.6.32-431.11.2.el6.x86_64/extra/snd-hda-intel.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped
/lib/modules/2.6.32-431.11.2.el6.x86_64/kernel/sound/pci/hda/snd-hda-intel.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped
They seem identical? Any suggestions where I could go from here? I'm currently recompiling the entire kernel and will just copy over the new modules and see if something better happens.
Thanks,
Chris

UPDATE: I compiled the entire kernel and then just copied over the needed snd modules into /lib/modules/.../extra Now I get this when I try to load the module:
Module signed with unknown public key ksign: module signed with unknown public key - signature keyid: 3000b37e8a34083d ver=4
Google suggests the following; neither worked:
objcopy -R .note.module_sig snd-hda-intel.ko or objcopy -R .module_sig snd-hda-intel.ko
Any hints?

2nd UPDATE:
Finally just installed the entire newly-compiled kernel, (reminded me of my old days with gentoo) with the only change being snd_hda_intel's CONFIG_SND_HDA_RECONFIG set. Audio works great (Beats Audio). Really wish I knew more about module signing so I could use the "stock" kernel".
I guess I'll probe further sometime with KMOD module compiling to see if it will somehow solve the signing issue.

Chris,
This m/l, CentOS-devel, is for discussions relating to the _development_ of the CentOS Project. You really should use the CentOS (users') m/l for your general query.
That said, please examine the output produced by executing modinfo on each of your modules.
Alan.
