All the owners of 3300 , please confirm if Audio from Tata Sky HD comes to TV ,when Onkyo HTS 330 is not in action ?
This is HDMI Audio passthrough , this feature is required when some time you dont want to 5.1 Audio setup to be ON, for example watching news on Tata SKY HD which is attached to A/V Recv.
Quoted by one of the reviews on Amazon: "You can also turn on the Audio TV Out option on and only use your TV's speakers if you don't want to use the receiver's speakers for some reason."
So, It should be able to do what u are looking for
Cheers!!
