facebook app sounds muting all other sound?

[McVitas]

Hello, does it happen to you also? When I play a podcast via podcast addict app or google music play app or whatever and in the same time I am in facebook app and click like on something then the sound of liking the post mutes the music or the podcast! I can miss a word or two because of that! I know it did not happen before. Is it the facebook app update which causes it or some OS update? I know that when I go by car and have a waze navigation running when it says the directions it causes the background music or podcast playing just lowers down the volume for a few seconds but I cna still hear it! The facebook app mutes it completely though.

That's normal, you could disable 

Facebook > settings > app settings > sounds > off
