Microsoft only provides free technical support for the first three months of ownership, and even then OEM cases are referred back to the manufacturer. Thus, if you want to contact their support department you'd have to pay $59. That leaves you with Dell and us.
If it were me, I'd start by trying the following:
1.) Line In and Microphone are, by default, muted for playback so you don't get the annoyance of hearing yourself speak should you be doing dictation. You'll need to unmute this by going Control Panel->Hardware and Sound->Change system sounds->Playback, choose Properties on your speakers, and check the Levels tab...unmute Line In.
2.) Go Control Panel->Hardware and Sound->Sound and make sure that Line In is listed as Available/Working under the Recording tab.
3.) Try setting it as the default recording source...same window.
4.) Use a third-party program, such as Audacity (freeware), and attempt recording the feed from Line In.
5.) Repeat with Microphone...it's essentially the same thing.
Hope this helps,
I have a Dell Dimension cp. Purchased in May of this year. The sound on this system is "Sigmatel Hi Dif.
I cannot receive sound when I play a cd from my cd player thru the line in on my cp.
Dell is very dis-interested in helping me solve this problem.
I am trying to find out if it is vista, dell or microsoft problem.
I cannot find a way to contact microsoft with out paying an ugdodly fee to find out wherein the problem lies.
Would anyone have information on how I could contact microsoft.
The said thing about this is that while I don't know a whole lot about these things, I found out that in an hour and half I knew as much as the tech I was talking with.
