Code:
localhost linux # /etc/init.d/alsasound start
 * Loading ALSA modules ...
 *   Loading: snd-card-0 ...
WARNING: Error inserting soundcore (/lib/modules/2.6.19-gentoo-r5/kernel/sound/soundcore.ko): Invalid module format                                       [ ok ]

And no sound. I deleted soundcore.ko and did 'make modules_install', but I still have the same errors.

useful parts of kernel config:

Code:
CONFIG_SOUND=m
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_SEQUENCER=m
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
CONFIG_SND_PCM_OSS_PLUGINS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RTCTIMER=m
CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y
CONFIG_SND_SUPPORT_OLD_API=y
CONFIG_SND_VERBOSE_PROCFS=y
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_AC97_BUS=m
CONFIG_SND_INTEL8X0=m
CONFIG_SND_AC97_POWER_SAVE=y


dmesg:
Code:
localhost linux # dmesg | grep soundcore

any idea? or any more output needed to be seen?

Thanks in advance

FcukThisGame,

It looks like you have updated gcc between compiling the kernel and the alsa modules. The kernel and its modules need to be compiled with the same version of gcc - the kernel checks.
Rebuild and reinstall your kernel starting with make clean.

The other possibility is that your module-init-tools needs to be rebuilt. I don't know why that helps but its fixed this issue for me a few times now.
