Change the volume and your ringtone

Tap the Settings (...) button at the bottom of the slider to change volume levels for Media, Call, Ring, and Alarm. For more info, go to New to Android: Surface Duo.
Caption preferences

Change your captions settings by going to Settings > Accessibility > Caption preferences and turn on captions by tapping Show captions.
Mono audio
Use mono audio if you’d like audio to come through one channel instead of two:
In most cases when you listen to music with headphones or through speakers, the audio will come from two channels, one directed for the left ear and one directed for the right.
If you’d like to combine both channels into one, turn on mono-audio by going to Settings > Accessibility > Audio adjustment > Mono audio.
Audio balance
Adjust the audio balance to determine if you want the sound to be louder on the left side, right side, or the same on both sides. To adjust the audio balance, go to Settings > Accessibility > Audio adjustment > Audio balance, then drag the slider towards the left, right, or leave it in the middle.
