@Nanette Irvine I use a wireless lavalier mic too. When I plug it into my phone, that is the only audio that gets recorded (as long as it was charged and on, 🙉) It should be there when you replay it. I have an android phone, when I go to replay on my phone it starts muted by default. If you can't here any audio at all, something probably went wrong. On my phone, if I forget to turn my wireless mic on, the camera will record using the phone mic. If this happens, what I've done in the past, is upload the audio file to Adobe Podcast and let it fix it automatically. I use the free version, though it is limited.
