I have a Dell Latitude E6410 running Windows 10 and need a little help.
The problem is when I use the external audio input (microphone jack) the audio constantly plays out the audio output (headphone jack). I have unchecked the "Listen To" box for this input and looked everywhere I can think of to stop this to no avail. In previous versions of Windows there was a registry entry I think called "Disable Microphone Playback" that could be changed to stop this but I can't find it in Windows 10. Could anyone please help?
