WHY DO I GET STATIC WHEN I TRY TO RECORD MY VOICE USING THE MICROPHONE JACK ON THE FRONT OF THE INSPIRON 546 ?

Make sure the device is not muted in the audio properties of whatever software you are running. Most audio programs will allow you disable it.

You should be able to go to Sounds and Audio devices in the control panel to test. Under the voice tab is a button to test hardware. Check there as well.

Hope this helps.

Check Bios settings to be sure audio is enabled, then go to control panel, click on sounds, and make sure sound is not muted

double click on the speaker and make sure that the mic does not have the mute box with an x in it.

I am pretty certain you have a card in your computer for it mentions a 7.1 speaker system.
If you put your service code in to do a search for drivers you will get the correct ones for your particular machine. Download install and reboot.
If you are not using six speakers and one sub woofer then the pink one in the back is the mic

This sounds like you have a voice morphing program installed. A morph program is useful for distorting your voice and special effects, but it also takes over your mic controls. Go to the control panel and choose sounds and audio devices, then look for the default device under sound recording and make sure your record device is the same model as your sound device and that it says INPUT. Another problem occurs if you right click your little sound/audio icon on the taskbar and choose open volume control then left click. Do that now and choose, options, then properties. Now on mixer device, choose one that says input. The white window on the bottom of that panel will show you several devices, check mark them all and click ok. Now manually select MIC as your default sound input device and close then try again.
