This a Dell Inspiron 5150? You got a Service Tag #?
Do you see an audio device in Device Manager?
The following c&p is possible solution someone else found in regards to their audio problems with an Inspiron 5150 (kind of long sorry about that- at the very bottom somene with an Inspiron 5150 follows these steps and find success):
Like a lot of people out there, just bought latest HP Laptop Pavillion V9000! Awesome laptop but Vista was terrible! Downloaded all the Drivers but sound could not be fixed! I was getting the same error as everyone else!
I looked for 4 weeks with no luck! I was about to go back to Vsita
Then a mate tells me to do the following in this order and SOUND NOW WORKS!!! Im rapt!
1. Download and install kb888111.exe file from
2. Download and install
First install Microsoft Universal Audio Architecture (UAA) Bus Driver
for High Definition Audio
3. Now install Conexant High Definition Audio Driver
It should then recognise the sound card after the kb888111.exe is installed and the rest should then work!!!
Good Luck and let me know if it works or not!
Cheers Nicko from DownUnder!!

Thanks! I have an Inspiron 5150 with XP...sound stopped working...installed the first two downloads you suggested (the 3rd would not load)....problem solved! Loss of sound seems to be a common problem with the Inspiron series.
