Media download before driver download????

Hello,

I have a HP Pavilion dv2940se

i recently had to upgrade windows--but since i was going from a 64-bit version to a 32-bit version, i had to reinstall all the drivers afterward, and someone who really didn't know what they were doing did it for me.....

Anyway, I'm having 2 separate issues:

1) the audio plugs on the front of the computer don't work (speaker and headphone sockets). the speakers work but, when i plug in headphones, or speakers into the headphone jack, it's as if nothing was plugged in at all.

I tried to download the correct audio driver for my computer--but it wouldn't complete the download because it said that the "media device" was missing... what is this media device and where can i find it?

2) Also, the little quickie media buttons just below the screen of the computer and above the keyboard don't work, either. I'm hoping it's not true that they only work in association with 64-bit windows... that would suck royally.

Anyway, any help you can provide will be so very greatly appreciated!!!!!!!!!!!!

Thanks in advance :D
