If any of you on this board are developers and have access to Apple's new iOS 5 beta, don't install it on any devices you use via USB in your Regal.
After installing iOS 5 on the iPhone/iPad/iPod touch (attached via USB) the music no longers comes out of the Regal's speakers it comes out of the devices speakers. Music information is still displayed on the Regal's screen and you can still control the music, but the sounds doesnt come out of the Regal.
Hopefully Apple will address this before iOS is released to the public in the fall.
