Confused on kernel updates

Hello all....

My problem is that I have compiled my sound card driver (SB X-FI) against a particular kernel <I can't immediately remember which one), downloaded the source etc, when a new kernel update is issued from automatic updates do I have to recompile against the new kernel to keep using my sound card?, and keep doing so as new kernel updates are released? I realize if I press the esc key I can choose from previous kernel installations, but that means I am forced to use an out of date kernel, with the obvious and attendant bug and security issues.

Thanks in advance

Yes. Any "driver" (kernel module) will be kernel specific and so you'll have to rebuild it whenever a largish kernel change comes out (specifically, when the -XX number changes). I don't think this usually happens very often though.
