Macbook Pro putting out low sound input Every app that I use, the speakers hardly put out sound even when set to full volume full blast. I went into sound settings and made sure the volume was up all the way and it sounds like it is on a mid-low volume. 

It is a 2018 15" Macbook Pro running OS Mojave.
First, make sure any volume controls in the app you’re using aren’t turned all the way down. Also, try playing a different audio file, CD, or DVD, or try playing the file or disc on another computer or media player to isolate the problem.
