@Ruhamah: What device do you have the soundbar connected to, and is the issue occurring when viewing/listening to all content? If you press the Sound Control button on your remote until 'Centre Level' and 'Front Top Level' are displayed, then adjust the volume using the up/down buttons, does this help at all? For further guidance, please refer to page 10 of the user manual by following the link below.
@Ruhamah: Standard mode will be the optimal choice unless you have rear speakers connected (for Surround mode) or you're gaming (Game Pro mode). Adaptive Sound mode automatically adjusts the sound field based on the characteristics of the content, so this might be worth checking out if you haven't done so already. Otherwise, based on the above, I recommend sticking with Standard mode if you're watching programmes/movies.
