audio help

i have a DV6345us and recently installed the new service pack for vista. i've been hearing a popping sound in my speakers ever since. i searched around this forum and it recommended to download the new Audio driver, so that's what i did. but evertime i tried to install it, the small installation window would just show up (after i follow the instructions), looks like it's installing but it never seems to finish. i left my computer on all night and when i woke up it still wasn't finished. i'm doing it again right now but it's been over an hour. now i don't have any sounds i'm installing sp39295.exe which was released 2008-05-20 version 4.33.1.60 A.

please help. Thanks in advance.

 

Can you manually up date the driver by pointing the device manager to the location with the INF's?

 

i tried that but it wouldn't work. i even tried to roll back the driver software but it just stopped working and said "not responding."

i shut down my computer, it didn't shut down properly and it started to diagnose itself. now it's my audio is working again, and of course the popping sound is back it doesn't give me the option of rolling back my driver anymore, and i'm too **** paranoid to update the software again. do you guys have the same problem after updating the driver?

 

What sound chip is it? Conexant, Realtek??
