No Sound via HDMI

[whataguywants]

Hi Alban,

I have set up the D3100 how I would like it and pasted the playback settings. I have the Sony AV Receiver in HDMI 0, a iiyama monitor in HDMI 1, nothing in the DisplayPort, pc stereo speakers in the back jack. I also have a Logitech camera and a Logitech unifying dongle in the two rear USB 2.0 plugs and an internet connection to the LAN port. I have nothing in the front plugs.

I use the iiyama as my main monitor and I assumed that I could route the audio to the Sony amp to watch movies on my TV simplyu by selecting it in the playback settings as my default device. Is this not possible?

Thanks & regards.
