Finally upgraded my AVR to a Denon-1611. Started with SPDIF optical cable for sounds and HDMI direct to TV for video to avoid handshake issues but got a popping noise in one of the speakers after 30 second commercial skipping in WMC 7 64 bit. So I decided to see what happens when I pass the HDMI through the AVR. The picture is fine and Nvidia control panel reports everything is fine with HDCP video but when I check audio status HDCP is NO and it will only pass 16 bit 48 kHz stereo. Since I only have a 2.1 system hooked up right now it is not the end of the world but I don't think this is the best quality and not sure what will happen when I put a BD in since I don't have one at the moment.


I would love to fix either problem.


Asus P5N7A-VM

with latest MB / HDMI / graphics drivers

BIOS is set for HDMI and followed Denon directions to reset HDCP

Worked on the issue a lot this weekend and fixed the HDCP for audio issue and can pass all multichannel audio fine. I have discovered that if I switch the HTPC output to stereo only when using SPDIF, cannot do this with HDMI, the pop goes away. Since I currently have a 2.1 set up this is OK.


I have 2 questions:


1. Has anyone else seen this or have any ideas about it?


2. Since I am using a 2.1 setup does this really matter, is the conversion to stereo from multichannel so straight forward that it does not matter if the HTPC does it or the AVR?


When I get some more time I am going to add some speakers from another room to make a temporary 4.1 set up and see if the pop still happens when the HTPC is delivering multichannel audio.


FYI, I am cross posting in the reciever area.
