Iphone cell phone to ask whether the output audio data via data cable to the amplifier or stereo

If you can export it, can output 5.1 channel audio it?
If you can output, then the people to speak against the iphone can immediately output to the amplifier as well?

iphone does not support the development of hardware and system-level contact, which can cause instability in the system, as well as security issues ... If you want to develop the hardware, please use the Android ...

That this thing the way people speak audio output is not supported. So whether it supports playback of 5.1 channel?
