Vista - Speaker Help

Hi all,

I have a 2.1 Dell speaker system running from a High Definition integrated
sound card, and I was wondering if anybody could give me some advice as to
how I can improve the bass. My sub seems a bit quiet, and I'm still just
getting to grips with Vista.

One more question, my computer came with Sound Blaster Audigy Advanced HD
software. I have tried to install this, but it says my audio drivers cannot
be found. This cannot be true, as the sound on my machine works fine.

Thanks very much, and I apologise if I'm missing something very obvious here
- thats just me
