Is there a way to override the 30 pin connector which disables the internal speakers. I just bought a micro projector which is a cool device. It is connected through a 30 pin connector with a composite video out incl sound. Unfortunately the internal speaker on the projector is tiny. The Iphone built in speaker do a better work.

And yes, I have bought a separate loudspeaker that can be connected to earphones out. Sounds great but is somewhat bulky for traveling. Using the internal iphone speaker would be more convenient.

I have been looking for an app, mod or fix that would allow for choosing sound out/internal speaker, but to no avail.

I am grateful for any help. Maybe there is a simple way but I have failed to find it after a weeks search.
