How do I mute all sound in duolingo?

I like to listen to music while learning languages but Duolingo's text to speech plays and interferes.

Welcome to Android Central! I just tested it, and I'm not sure you can selectively turn off Duolingo's speech, since it's an integral part of the lessons. You can try reaching out to the Duolingo developers about this.
