Netflix and Marantz AV7005


I have a Samsung smart tv hooked up to my Marantz AV 7005 pre-amp. When I select Netflix on the tv ,the netflix comes up with audio, but audio from the previous satellite channel also plays in the background. I have the hdmi1 arc out connected to my set top box in on the Samsung TV.

I wish it were that simple. The Internal speakers are turned off.But thanks for the response .
I assume that if you turn off the sat box the audio drops as well? If so that is one fix, but obviously you have able through somewhere. I think your best approach is start unplugging the HDMI and/or audio connectors one by one till the sound stops. Then try a different cable on that connection. You mention having HDMI 1 connected direct from SAT out to TV in, do you also have a SAT out to the AV7005 and the a HDMI from the Av7005 to the TV? If so why the direct SAT to TV If the TV speakers are turned off?
Your Marantz probably has an audio pass through feature that needs turned off. Is the Satellite hooked directly to the Marantz?
