App doesn't record internal audio

[titooo7]

I think it's because it's missing the following. https://developer.android.com/guide/topics/media/av-capture

I forked the app and tried to implement it to it can record the mic + internal audio but I failed...

Just fyi, this app can record mic + internal audio succesfully: https://github.com/crakaC/MediaProjectionSample
I was wondering if you can add the same method to record & mix both audios your project?
