Echoing Media On Galaxy S7???

[EmieHB]

So just today, my phone sound (media) is echoing. Like how your voice would in a bathroom or other buildings. Ive gone throught my settings and turned things on and off and nothing seems to fix it. I e restarted my phone and its still there. Ive never dropped my phone in water. I dont think its the speaker at all but some setting in my phone. It only happens when videos are bing played that i know of so far. Almost like a echo voice filter. This has never happened before. Any ideas?
