I have a VGN-FZ145E model laptop. Dual Core 2GB ram 160gb hd.

I researched online and found many tutorials and tips for doing this. I currently am running a dual-boot Vista/XP on seperate partitions.

I was able to get sound working by using some KB1xxxxx.exe file then installing the necessary driver (Sigmatel High Definition Audio).


The sound works now, however the headphone jack does not. You can plug anything into it and it does not disable on-laptop sound or put any signal into the headphones.

Under System Devices I have the SigmaTel High Definition Audio CODEC installed properly, but under unknown remains the High Definition Audio Bus.

I have tried searching google, and installing different drivers for the hardware from other sources with no luck.

Any help or suggestions would be greatly appreciated.

Everything else is working fine otherwise. I'd really like to make use of my XP install.

Intel 965 Chipset.

I used the search feature and possibly discovered that there is no solution, but please help and offer any suggests. A person suggested "forcing" a driver to work in XP, is that practical and how do I do this?

Regards,

John.

I'd recommend contacting or visiting the websites of the individual hardware pieces and download the driver software. Thats how I downgrade most of my vista computers.
