Can't hear mic.

[cod500]

I was trying to record audio and plugged a mic into the jack but I can not hear any sound. If I open sound recorder and blow i can see the volume waves move but I hear nothing. I have tried everything in control panel but I can not get the mic plugged into the jack to work. When I go to sound hardware test wizard I can test it and hear the mic playback but not when i do anything else. A USB mic works but not the mic jack. What could be the problem? Thanks.


[Solved] After searching I found this. I put it here just in case someone else is having the same problem.

Ok. I found the fix in the Dell forums. For anyone else having the
same problem - no MIC control in playback, if you have a Dell Laptop
with a sigmaTel sound board, either Dell or Sigmatel, has added lines
in the regedit that effectively "turnoff" this option so that the
check box for volume control of mic playback does not appear as an
option. This is done so that the internal mic, if active, will not
cause a feedback loop because the internal mic is obviously close to
the internal laptop speakers. Of course, if you enable the mic, use
an external mic and external speakers, this is not a problem and you
can then monitor your vocal or recording, "live".

To enable this, you need to edit registry.

"disablemicfromplayback" shows a 01 value. Change it to 00.
"disablemicselect" shows a 01 value. Change it to 00.

Once you are in regedit, use f3 and just cut and past the above lines
to search. I think it disablemicfromplayback actually appears in the
registry twice so be sure to hit f3 a couple of times until search is
complete for both registry lines.

After values are changed, reboot, and volume control for mic during
playback will now be an option. By default, when the option appears
and you add it as an available slider, it will be muted.
