Using a microphone with computer

To use any microphone with your computer you will need to enable it in control panel. The following instructions are for Windows XP but are broadly similar for Vista and Win7

Click START, CONTROL PANEL, SOUNDS & AUDIO DEVICES

Click VOICE

In the Sounds & Audio Devices Properties window locate the SOUND PLAYBACK box and click the VOLUME button. Make sure that there is not a tick (check-mark) in the MUTE box against microphone in the list of devices and that the volume slider is at the top of the scale.

Also make sure that the MUTE ALL box isn't checked before closing the window.

Now click the VOLUME button in the SOUND RECORDING BOX. Here you need to SELECT microphone as an input source for recording (as opposed to un-checking mute in the playback controls).

NOTE if microphone is not listed in the 2 sets of volume controls click OPTIONS, PROPERTIES on the tool-bar and place a check against microphone in the list entitled 'show the following volume controls' and then click OK.

That should be it.

However - if you cannot get enough volume on the microphone you may need to purchase a pre-amplifier to boost the signal strength before input to the computer.

First, confirm your laptop has a microphone. I am assuming, as you have posted your question, that it does.
Go first to your Control Panel, switch to classic view if you are using XP and small icons if in Vista or Windows 7. Look for some icon such as Sound or Sound and audio devices and click to enter it.
Now here is some divergence in methods.
XP
Enter the tab near the top of the window labeled as Voice. In the Voice recording section, confirm that there is a Default Device. If there isn't, click the drop-down arrow and choose on if there is one available. Sadly, if there is not, then I do not know how to help you. My expertise lie more in Vista and 7.
Vista & 7
Once inside of Sound, enter the Recording Tab and look for some type of microphone. Double click on the Microphone and at the bottom of the screen, there should be a "Device Usage" area and click the box next to it and choose "use this device (enable)" and click ok.
Hopefully one of these two methods should get your microphone working. I apologize if it doesn't. More information on your part may be helpful.
One last side note. There are two jacks on most laptops. If you are using an external microphone, you may be plugged into the output jack as opposed to the input.

I found this on the Turtle Beach website: ________________________________________
Let's make absolutely sure that the microphone in your headset is working correctly. If the mic is working, a replacement talkback cable should fix it. If not, then please send in your name, shipping address, the name of the store where you purchased your X1 and the date (month/day/year) of purchase.
OK, here's how to test the X1 using the Microphone input on your PC:
1) Take the pink plug from the X1 and plug it into the pink jack (Microphone input) on your PC's soundcard.
2) Take the green plug from the X1 and plug it into the green jack (Front L/R Out or Line Out) on your PC's soundcard.
3) Take the USB plug from the X1 and insert it into a USB port on the PC (not a USB hub, please).
4) In the soundcard's control software, enable the Microphone for playback. In the Microphone > Advanced settings, enable the Microphone Boost. Make sure the Microphone is not muted (Mute switch is not enabled).
5) Adjust the volume for the Microphone to about half-way up.
6) Adjust the overall playback volume to about half-way up.
7) Put on the headset. Make sure the Mute switch on the X1 amp box is not set to Mute (the LED should be green).
Now speak into the microphone. Do you hear your voice in the headphones? If so, the mic works and your X1 headphones should be OK. If you still cannot get the X1 mic to work over Xbox Live, then you need to take a closer look at Dashboard settings and other connections, or check the integrity of your X1-Xbox Controller Cable.

******************************
In order to enable the chat make sure that the Mute button in the Off position. If it is on the ON position the Mic will not work.
Red = Muted Green = UN-Muted

If you're having trouble adjusting the Mic in Windows:
WINDOWS XP:
For Windows XP, there's a nice video on YouTube that takes you through all the steps of setting up your microphone: http://www.youtube.com/watch?v=Vissxo8furo

While in the Recording tab of the Sound window, you will see all options available for recording - Microphone should be one of them. (If you don’t see an option for Microphone, ensure your microphone is plugged into your computer using the jacks commonly located on either the front or back of the machine.)
6. Left-click on the Microphone option to highlight it. This will enable the Properties button toward the bottom-right of the window. Left-click on the Properties button.
7. You should see the Properties for your recording (input) devices. One of these should be Microphone.

Note: The audio devices you want to use MUST be present in these Skype device lists. If they are not, check the device connections and driver installations again.

2. Microphone and Speaker connections

Check if your mic (pink) and speaker (lime) jacks are in the proper sockets (it is easy to reverse them) and fully inserted (they sometimes stick only partially inserted)
If your microphone or headset has a “Mute” switch, make sure it is not on
If your speakers or headset has a volume control, make sure it is turned up
For test only you can use an earphone instead of microphone (really)! Just unplug the microphone, plug the earphone into the microphone jack, and talk into your earphones. (I know it sounds silly, but it might tell you if your microphone is defective)
A standard microphone plugged into Line In will NOT work.

3. Check audio in Windows.

XP: Start / All Programs / Accessories / Entertainment / Sound Recorder

Vista: Start [Orb] / All Programs / Accessories / Sound Recorder

Make a short recording with the microphone; you should see the level meters moving as you speak. On Windows XP, you can then play back what you recorded.

4. Once done, test with Skype Test Call (echo123).
