I have a Dell XPS M170 laptop that I love. And some time ago I upgraded it to Windows Vista Ultimate 32-Bit. It was a bit of an effort to get everything working, but for the most part I was able to find Vista drivers for everything.

However I did experience one issue. The integrated speakers worked fine, but the external headphone/speaker jack stopped working. On a lark last night, I checked Dells drivers and downloads site and lo and behold there are now new Vista ready drivers for the whole system.

I downloaded and installed them and everything is again working, including my headphones!

Lesson learned, periodically check with the hardware Vendor for new and updated drivers. It will save you some heartburn on occasion.
