Hi - For a complete /lib/modules/kernel-version to be missing seems
like a pretty big problem..

To me this seems a bit like you didn't have the right /usr/src/linux
link. Some programs use that link to determine where to put things or
what to build code against. If the link points to the wrong kernel
then stuff gets placed in the wrong location. Since you are using a
much older kernel here you are possibly more subject to that sort of
problem.

Yes - keep working to find the right answer.

This may be dependent onthe version of Alsa you are using. I am
assuming that you do have a /proc directory.  Do you?

On the other hand if Alsa didn't load then possibly that directpry is
not created.

Another sort of ugly possiblity is that your sound is coming from OSS.
Again since you are usign something older this could be happening.

Jack will not run until Alsa runs cleanly. I use Jack all the time. It
works very well, but it does require Alsa be up and going.
