I've noticed that some players accidentally have the microphone on, broadcasting sound without realising that they are doing it.
And not every player actually tells you that you have it on.

This happens for new players (who have it on by default and may not have found the setting) and experienced players (who had it on for a group of friends or something and forgot to turn it off). I have done it once myself, though thankfully someone pointed it out.

Whilst you could say it's a 'just be careful' thing, it is very easy to do if you use the microphone only occasionally.

My suggestion is to have an extra option in the microphone settings to have an Auto-off check box option. So if ticked, the microphone would still appear in the HUD when first logging in, but is muted by default. The players can still easily access the microphone when they need it, but it isn't automatically on when not.

If you wanted to expand the idea, you could make it a drop down, with a few extra settings for when the microphone would be automatically off;
- Always on (As it is now)
- On log in (Each time when you first log in it is by default muted)
- On new journey (ie. Each time you start a new journey in the arcade)
- Every level (A bit overkill, but automatically muted every level you go through)

I'm sure I'm not the only one who's accidentally left it on (I've heard some and pointed it out), and I'm sure I won't be the last.

Thanks for reading :)
