Setting up ACPI Volume Controls

Hello, I have successfully built an LFS system, and I have customized it very much via BLFS. However, I am having trouble getting the ACPI volume buttons on my laptop's keyboard to work.

What I have done so far:

• installed the acpid package - done
• installed alsa-lib and alsa-utils - done
• installed pulseaudio - done
• configured the ACPI screen brighness buttons - done
• get sound to work (i.e., actually play sounds) - done

What I am unsure of

• compiled the kernel with support for my keyboard - not sure if done properly
• configured volume buttons - not working

I have tried getting the volume buttons to work, but to no avail.

I have a Toshiba Satellite laptop.

Thanks.
