sound just stopped

so the other day i was wanting to experiment with some new things so i built a new kernel (wisely ? saving the old one). shortly thereafter i decided that the new junk wasn't for me and i switched back to the old on. i just changed the bzImage back to the original one. everything is fine again except now i have no sound!!! is there a way i can trouble-shoot this? i am using the same kernel i had before when sound worked like a charm. any reason why this would happen? i cant think of any other reason it would stop.

Whenever rebuilding the kernel, ALSA drivers need to be rebuilt.

but i never used alsa in the first place. i just compiled support for my card into the kernel and it worked just fine. never really saw the need for alsa

did you re-build modules for your trial kernel?

Perhaps the modules no longer match.

You might want to try to re-create your original kernel config (did you save it?)
and re-build the whole dang kernel and modules.

Its probobally a good idea to do something like:

cd /usr/src/linux
cp .config foo
make mrproper
cp foo .config
make menuconfig # turn back to old config settings
cp .config config-10-10-02
make dep
make bzImage
make modules
make modules_install

Make a habit of doing the cp .config config-mm-dd-yy
whenever you get a "good" kernel, that makes it easy to
re-produce:

make mrproper
cp config-10-10-02
make oldconfig
make bzImage...
