I have a few sound effects on my buttons, and when I tap on them, sometimes the sound gets played twice, and if I add a Release sound effect, both sound effects gets played? Anyone else noticed this or am I doing something wrong? Will build it on xCode now and test on my iDevice.. Thanks, Josh EDIT: This happens on my iDevice too. I have decided to get rid of the 'Released' sound effect, but my mute button plays the click sound twice when going from music ON to music OFF, the other way round it plays it just once?
