Having recently purchased a Vivitek HK2299 projector, I was very disappointed to find that there is no sound output (only picture) from my Pioneer SC-2024 amp and BDP-450 Blu-ray player, when trying to play various Blu-ray discs. Seems as though it may be a HDCP issue? The sound and picture work fine when the hdmi cable is plugged into a flat screen tv. When playing content from my Western Digital media player via the amp to the projector, both sound and picture are perfect... very fustrating!!!
The projector was purchased in the States, the amp and Blu-ray player was purchased in Europe - could this be an issue?
Any assistance will be much appreciated!

So you have no issues with video passthru to the projector?

I would think that maybe this is a Pioneer issue as it needs to deal with actual 4K video and perhaps the receiver (Pioneer) is not able to process audio when a 4K signal is being sent through the receiver. There is a lot of talk on the receiver's web page about 4K pass-thru, but I'm not sure what that means as 4K needs to have the audio stripped off of it and passed onto the projector.

The Blu-ray player does offer dual HDMI outputs, but you shouldn't need to use them with this receiver.

But, perhaps when the Sony is hooked up to the Pioneer and putting out 4K video, it defaults to sending audio over the secondary HDMI connection, and then doesn't work properly?

I'm not completely sure how all of this goes together, but I would probably start by looking at the sound and audio settings of the Sony.

The projector should have very little to do with it as it is not supposed to register as an audio device to the system, but it will come up as a 4K display, and that will impact other gear in ways I'm not completely sure about.

Many thanks for your thoughts and info - after much frustration I've managed to use the co-ax audio output from the Blu-ray player to the receiver.
