How to mute media and sounds when using Google Voice Keyboard?

[mcraine]

Recently I noticed that when I use the Google Voice Keyboard to do a search or enter a text message, other sounds are no longer muted. Two that I've noticed are Spotify and playing podcasts. When I hit the microphone, Spotify or podcast continues to play and the keyboard recognizes sounds and enters them. Very annoying. This started several weeks ago on my Nexus 6P. Prior to that, when I hit the mic button, the music or podcast would pause while the Voice Keyboard was active. I recently got a referbished 6P for other reasons. Same problem. I also reset the phone. Same problem. Everything else works perfectly. Is there a setting somewhere for this?

Thanks for any help or suggestions!
