Computer chassis front panel microphone No sound how to solve

1. Here we first try to connect the microphone to the front panel, and then use the system with the audio to debug, specifically, we click on the computer in the lower right corner of the audio icon, and then the pop-up menu in the corresponding menu should be detailed as shown in the following figure.

2. Now we go to the "main volume" panel, at home we see if there is no mute option, if we have to cancel, and I also have the microphone related to the hook or no sound.

3. Suddenly think it will be a driver, so I went from this step to the right track, I downloaded a driver wizard software, and then we update.

4. After the installation of the driver installed on the Realtek HD Audio manager, open the inside of the settings and get some, also did not disable, there is no mute, but still no sound.

5. Installed the Driver wizard did not solve, and then I found in the back of the chassis on the outside of a line like audio, I tried to connect it to the corresponding interface, the results found that there is a sound oh.

To sum up, we should first consider the problem of hardware, some chassis front panel volume needs to be in the back of the board can OH.
