I get picture but no sound from my HTPC when I connect it with HDMI cable to my Yamaha RX-V565 receiver.
In the option menu under signal info it reports "No signal" under format, and are sometimes flickering between "PCM" and "No signal" although no sound.
However, both picture and sound works fine when I connect the HTPC directly to my TV with HDMI. I also get sound if I connect the HTPC to the receiver with SPDIF. I have also connected other HDMI components both to the TV and the receiver, like a blu-ray player and a digital cable TV decoder and both picture and sound works fine.
It seems like the receiver simply ignores the HDMI audio that is coming from my HTPC
Any ideas or suggestions of what I should do in able to fix this issue?
