Front speaker and mic jacks dont work - Windows Vista Basic

The audio jacks on the front of my Compaq Presario SR5030NX computer
don't work. They work o.k. on the back. I've went through all the
settings I can find, but nothing changes. I see this subject came up
a few months ago, with this suggestion:

"Right click on the Speaker icon in the Taskbar and select Recording
Devices.
Right click in the Recording window and select both "Show Disconnected
Devices"
and "Show Disabled Devices".


Does the rear microphone jack now show up? If it does, click on it as
press the
Set Default button and use the Properties and Configure buttons to set
up the
microphone.


Have you looked in Control Panel or your All Programs list for an
Audio Manager
applet?"

When I tried the suggestion the 2nd paragraph, under Jack Information
it still doesn't cause information to display anything about the front
jacks.

I've tried to talk to Hewlett Packard about this, but it seems to have
them baffled.

It is possible that the front panel ports are not even connected to the
headers on your motherboard/soundcard. Look inside the case.

Synapse Syndrome -

You may be on the right track. Last night I was playing around
with it and got it to work fine, but this morning it was out of order
again. I think maybe there is an intermittent connection someplace
and I'm going to have to search for it. Thanks for your reply.
