No Sound via HDMI

[whataguywants]

Hi Alban,

The screenshot I have posted is of my playback devices with my Sony AV Receiver DH-520 plugged directly into the HDMI port of my laptop. As you can see the Sony AVAMP audio is present. The problem is when I plug the Sony directly into the D3100 the Sony AVAMP disappears.

I have also attached another log which I produced with the Sony device plugged directly into my laptop.

Thanks & Regards
