No sound with ARC

[beecksche]

Hi,

i have a Samsung UE40C6200 TV with Software Version T-VAL6DEUC-1017.0. 

The TV is connected with an HDMI to a Teufel DecoderStation 7. I'm not quite sure which version of HDMI cable it is. It only says: "Highspeed with Ethernet"

I want to receive the sound from the TV on the DecoderStation with the ARC. So i enabled the CEC and ARC option on the DecoderStation. On the TV I also enabled CEC and set the "Receiver" option to "on" (Tools -> Anynet+ (HDMI-CEC) -> Receiver)

On the DecoderStation the Input is automatically switching to ARC, but I don't hear anything. 

I have also tested another HDMI cable without success. With my remote control of the TV i can change the volume of the DecoderStation. 

Can someone help?

Thanks!

I’m having the exact same issue. I run the tests and sounds works, but when switching to any source on my receiver, the video shows but no sound. Were you able to find a solution?
