The driver is already install but the icon of sound still red cross like image attach file, I already plug in the headset, any one please help me?

Well, one way or another, your computer isn't using the device, so have you checked to see if it's disabled in any way? right click the speaker and go to playback devices, it'll come up with a list of your sound devices, make sure the one you're trying to use isn't disabled (right click to change that) if you're unsure which is yours, just enable them all lemme know if that helps at all
