PR Freeze on loading screen and audio options

[Salvakiya]

Hi all. I finally got PR on my vista computer and I got it to run. Unfortunately I cant play the game because when it loads client data I hear the music mess up and it starts repeating a short section of the song over and over and it is stuck there.

If I try to access the audio options menu I get the same thing. However every other menu works.

I automatically assumed that it was an audio driver problem so I updated my drivers but it still does not work.

here is my computer info:

Digital Mobility
HP G50-108NR Notebook PC

intel graphics media accelerator 4500m
with up to 765 MB dedicated memory

integred 5-in-1 digital media reader

other important information

DRIVERS:

if anyone can help please do

EDIT: oh and I forgot to tell you I am using the newest version of PR


Edit2: I found out that BF2 and PR were messing up on the same things. I also found out that I could play them IF I DISABLED MY AUDIO. but the problem with that is I cant hear anything. Is there a way I can fix this issue?

my two audio devices are:
Conexant High Definition SmartAudio 221 (this one I have disabled)
Intel(R) High Definition Audio HDMI

Both drivers are up to date and I dont know what else to do.
