I have connected my iPhone to my Windows 10 PC via pin plugs in order to record a voice mail from a deceased friend. When I try to record this vm with WavePad, it doesn't detect any input. I have tested my microphone input & set all the Wave Pad & Windows settings to correspond with the proper microphone input....to no avail. When I press Record, I get the message: "The recording has failed to start", even tho I can hear the input over my PC's speakers. Please advise on how to troubleshoot this issue
