Can't pick up Zoom on bluetooth speakers

[Roger_Blair]

I use the Zoom app on an Android tablet. Recently, I aquired a Bluetooth speaker (no microphone). I can play music in my speaker but cannot pick up Zoom sound; the sound only comes from my tablet speaker. I probably need to change Zoom's output device in the audio settings, but I can't find the settings in the Android app. How do I access the audio settings in the Android app?  The Aondroid app doesn't display an up arrow net to the sound icon, unlike the desktop app.
