Hi How to fix an internal/headphone microphone for use of eg. Skype (asking for dpv.setup.exe) No need to load this exe, you can fix it in a much easier way. I had this problem. My microphone was set by the program on MUTE! To fix it :First check if your internal microphone works: 1. Rightklick Start- Programs- Accessories-Entertainment-Sound recorder. 2. Klick red(round) button on Sound recorder and talk. Play it back by klicking the arrow in the window. Does it work? Good. If not, there is a problem I cannot help you with. 3. Redo the same with a headset (earplugs and microphone). It should still work. Now you know it will work on Skype etc. Then the fix: 1. Star your computer in safe mode (press f8 when you start it up when the first "blue" page comes up). Go to Start-Settings-Control Panel-Sound and Audio Devices-Voice. See what your computer uses as a microphone(note the name of the device). Check that it is'nt muted. Then go back one step to Audio Devices-Hardware and check the same thing. There should be a tab there saying Microphone mute. I removed the tick and it worked like magic. Next time start the computer in normal mode. Good luck IJ
