Why does the iPad disable all volume controls when you connect to a Bluetooth audio device? Am I missing something? I have a Belkin BT music receiver that takes an audio signal over bluetooth and outputs it via headphone jack / RCAs to a stereo. This makes the iPad an awesome music playing device for remote control of your music collection... EXCEPT that when it connects to the Belkin, both the hardware volume controls and the iTunes volume slider are disabled. This does not happen on my Macbook but the iPhone 3 also disables the volume control. I've been on the phone with Apple and they told me to put in a "feedback" request with a description of what I think it should do. Basically it shouldn't disable the volume controls! Does anyone else use the iPad with a BT audio device?
