But don't want to download and install another APP, just use the camera APP and Video whatever. The audio will be picked up to share.

Lori, remember when I sent you that one song we had recently been practicing, working on, and there was a slight video in the beginning? That was how our BASS player recorded the audio. I asked him the other day, if he used an Recording APP or whatever, and he told me that is how he did it. So no need to install another APP on my new Amazon Fire, if & when I want to share again :-)
