Sound bar issue

Not sure this is the spot to ask but here goes. I have a Philips soundbar, series 5000. i have to crank it up to hear anything but if i just use my TV, I don’t have to put the volume as loud to hear. I got hte soundbar because my TV wasn’t always loud enough. I’ve tried HDMI, AUX in, and bluetooth. they all work but none make the volume very loud.

maybe you can ask here website
