Canon 550D external flash and liveview

[davholla14 1]

My Canon 550D's liveview does not work with external flash. I have looked on line without success is there anyway to get this to work? If not what is the cheapest Canon that should work?
I have tried Yongnuo YN-14EX Macro Ring Flash, Neewer® *COLOR-SCREEN* E-TTL and Yongnuo YN-560 II Flas.
I am not very optimistic but maybe someone knows what to do.

Does the 550D have "Silent Shooting" mode or "quiet" mode? If so that will disable the flash when in LiveView.
