HI-PAD MAX stereo issue

Hello. In landscape, the stereo audio is very weak out of the right hand side speaker. When viewing video content in portrait the stereo sound appears equal.

I’ve tried altering the audio settings by forcing more volume into the right hand speaker but this isn’t really a fix and of course it then affects the sound when viewing in portrait.

Anyone else have this issue?? It’s also the same problem when playing games in landscape.
