[gentoo-user] alsa-driver: "Unknown symbol in module" error

[gentoo-user] alsa-driver: "Unknown symbol in module" error

[Grant]

My Dell Vostro 1320 doesn't mute the external speakers when headphones
are plugged in.  These guys seem to have fixed the problem by
upgrading to the latest version of alsa-driver, alsa-lib, and
alsa-utils:

I'm on the latest hardened-sources in the tree which is 2.6.29.  I'm
thinking I need a newer version of the snd-hda-intel driver and I
don't want to switch kernels.  I tried to switch to the latest
alsa-driver, alsa-lib, alsa-utils, and alsa-headers, but I ended up
with a bunch of "Unknown symbol in module" errors.  The error is
described here:

http://www.gentoo.org/doc/en/alsa-guide.xml

but the 2 solutions (rm -rf /lib/modules/$(uname -r)/alsa-driver and
some device_mode stuff) don't work for me.  Does anyone know how I can
fix this?

I'm just guessing here, but I'm thinking that deleting only the alsa
modules may not be good enough.  I'd try deleting all of the modules
and recompile/reinstall them.

I can confirm that the problem is fixed in 2.6.31-gentoo-r2, but I'd
really like to keep my hardened kernel.  Any other ideas as far as
getting alsa-driver to work?

Wait a minute, are you installing the alsa-driver package from portage?
Don't do that, use the alsa drivers that come with the kernel sources
instead.

It turns out there is 2.6.31-hardened-r2 in the hardened-dev overlay.
I installed that and the included alsa drivers are current enough to
solve my problem.
