Onkyo receiver - help needed

[FilmFanSam]

Hello everyone

I recently bought an Onkyo HTS 4505 which is a receiver with 5.1 speakers & active subwoofer.

When starting a BD / dvd / cd in my player, the sound will not come on for about 2 seconds. this also happens when pausing a film and pressing play.

is this normal? if not, can it be fixed and if so, how?

any help much appreciated - this is my first venture into the audio/receiver world and I want to get it right from the start!
