First thing to know is, did music play normal? In other words, can you use a computer to listen to the song? I don't know what you mean is a chat does not work or a sound recording does not work, follow the following steps to try: 1, your
microphone in the figure below, there is a high, click on it, there should be two check boxes, how did you uncheck? If you don't check at all, please don't pipe it. <B> above and to the left in the figure2, you click 'options'-'Properties' in the open 'Properties' dialog box, choose 'single recorded' radio button selected in the box below 'microphone' and then click OK. Recording Control Panel appears (you playback control panel shown in the figure), the interface that appears with your diagram is essentially similar, but note that the mute here becomes a choice, you try to choose a microphone and volume to its maximum, and then see what effect? Similarly the microphone below also has a high, do the first step the same thing and then try. If you have done the steps above does not help, try this: right-click the computer speakers at the bottom right of the screen, select 'adjust audio properties' in the open 'sounds and audio devices properties' dialogue box, select the 'voice' tab. Click on the bottom 'test hardware', and then follow the prompts, if passed, it means that your hardware no problem, and the driver was installed. If the tests pass in place, keep an eye on it and then follow the instructions it make any adjustments. If it is a driver not installed, reinstall it again. If you do not install, I am sorry, it is difficult to express in words clearly, please look for people to help one understand the installation. You can right-click on 'my computer' select 'Properties', and then open the 'hardware' tab, then click on 'Device Manager' in the Device Manager, there should be no yellow or Red Cross or an exclamation point appears, if you have to prove that you a device that is not working properly, of course, does not rule out is your sound card.
