Disable all program sounds
<p>I would like to have a setting to disable all sounds coming from my program.  I know I can set a global ivar and write if statements for each sound but I was hoping there was a something I could set in the appdelegate to disable all program sounds.</p>

<p>I have played a couple of games that allow you to turn game sounds off.</p>

<p>I am using AVAudioPlayer for longer clips and basic Audio Service System Sounds for short clips.</p>
