As I've said before, someone on our local facebook page had a similar issue and videod the sound and how there was basically no bass and adjusting the equalizer made no difference as well. Half his speakers weren't even putting out sound. On our suggestion he took it to the service centre where they acknowledged the problem and did 'something' to fix it. Whether they re-flashed the firmware or what I don't know but it's a software issue. You could try various levels of reboot to see if it helps.
Can confirm - when I move the slider to the rear speakers - basically all sound disappears except for what sounds like a tweeter.
