I connected our Dell 5060 PC to our year-old Sony 900e TV. The system detected the Sony TV. When I investigated available sound settings, 5.1 channel audio was indeed available to be sent to the Sony.
The 5060 identifies our 11-year-old JVC DLA-RS1 projector as display type "ILAFPJ--XH", but, unlike the Sony TV, Windows settings is preventing 5.1-channel audio from being sent via display port. Only 2-channel audio can be selected and sent.
Older versions of windows on older PCs would somehow "assume" that the HDMI signal was going to go to some kind of receiver prior to going to the RS1 and they delivered 5.1 regardless of the fact that the projector couldn't play it. I know this is true because our old HP Slimline HTPC with Windows Vista used to output 5.1 audio to the RS1. Unfortunately, that PC's motherboard failed a couple of months ago and that is why I purchased the Dell 5060 to replace it. So far, the Dell is nowhere near the HTPC that the HP was.
Will the Dr HDMI "tell" Windows 10 in the Dell 5060 that it is connected to a device which can accept a 1080p 60Hz signal with 5.1 audio via display port? Put another way, can the Dr. HDMI tell the Dell that it is connected to a new Sony TV instead of an old RS1? (BTW, I use a male display port to male HDMI cable to connect the PC to an HDMI switch, which then connects to the RS1. The Dell correctly identifies the JVC RS1 THROUGH the switch.)
Is there a less expensive HD fury device that will solve this problem? Do you know of any way to trick Windows 10 into sending 5.1 audio to our RS1 projector without having to install an interface? Do you know if installing a sound card with optical spdif output would force Windows to make 5.1 audio available through the sound card?
