I've just recently installed Fedora Core 3 onto my laptop and I can't get the sound working. I've searched through the forums and I can't find any solution.

I can't start KDE since it won't get past 'Initializing Peripherals' (due to sound card problem) so I've started using Gnome. Using the sound icon in the bottom right I've made everything 100% and played with the mute buttons. I've also tried using alsamixer and doing the same thing. Still no sound. When I try to do the autodetect it finds my card successfully but the test sound does not work.

I've used yum and upgraded all packages, which included the latest ALSA drivers and Fedora kernel (ran yum check-update and yum update)

When browsing the forums I came across a few commands that people wanted the output from so I here's the all relevant info (at least I think):

./lspci

snd_page_alloc 9541 3 snd_intel8x0m,snd_intel8x0,snd_pcm

I read on one page that there was a way to enable/disable onboard sound in the bios but I can't find that on my system (Phoenix BIOS).

I'm also told that this is the classic newbie question

As a side note.. how do I enable /usr/sbin and /sbin to be in my path permanently (not set it each time I boot my machine) so I can run these 2 commands easier
