sound on my MacBook pro suddenly low

The sound on my MacBook Pro is suddenly low when turned all the way up. Of course I have set F12 at its highest and the same in Settings-Sound. Suggestions?

MacBook Pro with Retina display, macOS High Sierra (10.13.3)

1. Reset NVRAM/PRAM couple of times. http://support.apple.com/kb/PH18761

2. Reset SMC. Choose the method for “If the battery is non-removable”.
