Sound card problem

[Guest]

So I installed Windows Vista Buisness on my dell inspiron 9300 laptop because
it is what my school offered through MSDNAA. I purchased the Buisness to
Ultimate Upgrade and upgraded the install of Windows. Upon instalation, i
lost the ability to get sound out of my headphone jack! I cant figure out
why, i tried reinstalling the driviers for the sound card (SigmaTell C-Major)
and am still having the problem. I can still get sound of my on board
speakers fine, but if i plug in headphones or outside speakers, I lose it
all. I was able to get sound out of the headphone jack before i upgraded to
ultimate, so this is an issue cause either by upgrading or by ultimate
itslef. Has any one else had this problem? Does any one know how to fix it?

I have the same problem except I upgraded from XP. Please can anyone
help?

What is the "same problem"?? The subject is vague and your post is
even more vague.

Most people who are looking at your reply are NOT using Vista Forums,
they are using Microsoft's groups on the MS server or one of those
groups that have been propagated to Usenent servers around the world.

Thus they don't have easy access to all the posts you see, and they
have NO CLUE what you are talking about.

The cure: QUOTE WHAT YOU ARE REPLYING TO.
