Some possible issues and fixes for you. 1. Do a software update, this is found under General settings normally. 2. Update YouTube app and Netflix. Try a different app that would normally always have perfect sound.,Example: Pandora 3. The speakers may be going out on your phone. This would require the back glass to be removed and the speakers replaced. If I am right this will either be next to your Charge port on a flex.
