Apple TV 3, SPDIF connection to Majik DSM

Hi All

As said in subject, i'm trying to get an Apple TV ver. 3 to play through the spdif connection to my Majik DSM.

I have hooked up the Apple TV box via the optical output (spdif) to the spdif1 input on the Majik DSM - but no sound at all.

There's not much I can do on the output on the ATV3 box. I can choose "Auto" or "16bit" in the audio output. Thats it.

The ATV3 box plays fine over the HDMI output to the TV, so function and playback on the ATV3 box should be okay.

Any ideas?

Best regards
Allan
