Various factors can contribute to the volume level difference. If the 
recording uses a format that is supported by your sound system (for 
example AC-3), and you have the correct settings in android setup, and 
you select mediacodec, the encoded stream goes directly to the sound 
system, where it is decoded into surround sound. In this case, the 
android device has no control of the volume.

leanfront does nothing to affect the volume, whether or not it is passed 
through to the sound system. If you select ffmpeg decoding, or you 
select auto and the system selects ffmpeg, the audio is decoded by 
ffmpeg and sent as PCM digital audio to the TV. Nothing is done to 
affect the volume. To change the volume would require modifying the 
digital stream.

There may be android settings on your device (e.g. quiet mode) that let 
you adjust the overall audio volume or volume range.
