Hello,
I call on you because I have a problem with my TV Samsung UE65MU6405.
My TV is connected to an Onkyo receiver (TX-NR636), and I have the sound on my Focal columns with the ARC function.
On the other hand, as soon as I connect my video-projector on the receiver (in hdmi), the ARC sound of the TV is cut every 10 seconds ... a shot that passes on the columns, a hit on the hp of the TV. And as soon as I unplug the hdmi cable from the video-projector, everything becomes normal again and it works perfectly well.
I said that I have activated the ARC and CEC function on the TV and the recevez.

Thank you so much.
 
Solution
You could try turning off CEC.
Does it happen if the projector is off when you connect the HDMI cable?
They may assume you won't select ARC as your audio source if the projector is turned on since you can't see the TV video content on the projector. You could try using the TV optical audio out instead of ARC.
