iPlay CG uses the device's sound ennige so sometimes it may lock up for unknown reasons. Go into sound settings, slide the volume to maximum and flip all the switches off and back on. This will refresh the sound ennige immediately.
Honestly, the nicest group of guys I've ever met. Tons of fun to hang out with and party with. I absolutely love them. One of the smaller fraternities, but definitely one of the most fun. Their freshmen this year are super cute too :)
