Sometimes I can listen to anything, how can I turn off sound questions?

I fail lessons when I'm in an area that I can't have sound playing (a boring lecture, a library, waiting room), I think it's a bit ridiculous! There should be an option to allow or disallow sound-related questions temporarily no?

Set "speaker" to off.
