I got a few problems with my new laptop, Asus G51JX especially with the built-in microphone: 1) The realtek software to configure the volume of the microphone is not working correctly. Whenever I lowered down the volume of the microphone, the volume will go back to 100% after a while. 2) The microphone is not working correctly. Whenever I tried to video call using various IM application like Skype or QQ, everyone complains that the background noise is very loud and my voice is very soft to a point that it seem my voice is not picked up by the microphone. I have tried various setting from the realtek software on the volume, mic boosting and the noise supression function but none of them work. I even tried Skype's test call to record my voice and playback. When playing back I really can't hear my own voice. The only time I could hear my voice is when my mouth is almost touching the microphone. May I know could it be a software issue, and if it is a software issue, which driver should I update? The sound card or the webcam driver as I do not know the microphone is tag along with the webcam or a standalone one. 3) There is a little hole on the top of the laptop lid which is behind the camera, may I know what is the function of the hole? 4) There is a second hole beside the microphone hole, is it link to the microphone as well? Does anyone experience the same microphone problem as me?
