[ubuntu] Record Video & Audio from Android Phone?

Hey folks! I just started a new job that requires me to record video clips from mobile games. I did several hours of research into this, and I simply can't find any easy way to capture both video and audio from my Android phone using Linux. I did find:

• adb command to record only video
• Android apps to record using a *rooted* phone

I really don't want to try rooting my phone because of the danger of bricking it. And I do need audio, not just video. So my question is: with Android being Linux-based, there has to be some Linux app that grabs audio and video, right?

What am I not seeing?

Hope you can help me.
