Red Speaker won’t go away.

Hey guys,
I have the red mute speaker in the top right corner. On a fire stick.
I have tried adjusting the volume when the movie starts and this does nothing. I can adjust it all I want and it does not move. Yes I did make sure I saved it as default. I do have a mini blue tooth keyboard. But the volume keys seem to be no help, neither does the mute button. The unit is about 5 weeks old. So I have a hard time buying that the mute button is stuck. I am NOT a programming oriented guy..that being said I use the pre downloaded stuff that was on Kodi when I got the fire stick. I would really like to avoid wiping kodi and reinstalling as I feel it’s something better handled by people who actually understand the process lol. So what I’m getting at is if anyone has a idiot proof easy fix? I would be forever great full. I am not dumb and can follow step by step directions..but please be advised that other then clicking kodi and then movies/tv I don’t know a whole lot about it. any help would be welcome. Thank you in advance!!
