use buttons to control audio

[diarmuidmcg]

so currently the background music and game sounds go on when you start the game. but we have music/sound on/off buttons. can you use those buttons to control the audio? so if music button is off, we dont want the background song to play. similarly, if the sound button is off, the apple eating sound and the losing sounds shouldnt play.

also remember, one can stay on while the other is off as well. or both can be off as well, both can be on as well (which is how it is rn)
