sound and display

I turned on my x box 360 today to discover there was no sound? I could not work out why as nothing had changed since last use. Checked all wires and connections. Then as recommended I disabled the display discovery, and it seemed to work, until I bought a film, now it says 'secure HDCP link not found' it continues to play the film with no picture. So if the display discovery is enabled I have picture no sound, and if it is disabled I have sound, no picture :-(........I can however watch and hear trailers....WTF?.....please help....
