Guys, I've figured why there is no react from Sony, they can't hear us 'cause theirs phones have low volume bug too. 
Yes.. I am experiencing it with my Z5 Compact also. Mine is top speaker volume lower than bottom speaker. Especially playing media apps. When checked in service test, sounds liek the top speaker volume is limited by something
Have done almost everything to repair and reinstall the re-issued .376 from scratch.. still the same..
Come on Sony?!?!
Just an update on the issue. Media volume has balanced out itself (Youtube, Music,Games,...) overnight. Yesterday night I turned off all the volumes (ring, media, alarm) then restarted the device. After that I turned them back up to the correct levels. It still didn't fix the problem then. However this morning, the media volume suddenly restored to correct balance on the speakers.
But I also checked on the call ringtone, the balance on this however, is still towards the bottom speaker
Additionally the media volume on Youtube, VLC Player and MX Player still seems to be lower than the built in Music app. Game volumes are normal though. Dial pad tones on phone app are very loud and balanced, annoyingly much louder than Android 6.0.
Weirddd... I'm just gonna leave it be until Sony ACTUALLY irons out the volume bugs in Nougat.. Hopefully Sony REALLY LISTENS this time!!!!
