Please have audio disabled by default

[tjex]

In this world of terminal applications, we're not used to having sound output. Error sounds, or any sounds are pretty rare these days in general. Mac has a tiny "blip" sound by default in some error actions, linux nothing, Windows a soft chord.

I almost hit my coffee mug over onto my raspberry pi after the error sound from cb blasted from my speakers.

It's really not that cool. Clearly had a lot of care and consideration put into this project, please consider applying that same care in this case!
