You might know that the Logitech HD Webcam C510 contain an integrated microphone. I have also bought the same model for my computer. My PC is running with Windows 7 Ultimate. I have installed the driver for this webcam but it didnít install the audio driver for that webcam. I have tried several times but the windows 7 doesnít seems to be installing the Audio drivers anyhow. The sound section of the control panel also doesnít show this mic. When I looked into the device manager it shows me that there is an unknown device. However I cannot update the driver of that unknown driver. Can anybody help me?
