HDMI Splitter...Sending Audio-Only to Processor
.
Is there a device that will allow me to split an HDMI signal? I’d like to run the HDMI cable video signal from my projector directly to my streaming device and send only the audio signal from my streaming device to my processor.
My Blu Ray player has 2 HDMI outputs...one output does audio and video, and the other output does audio only...it allows me to plug my blue ray player directly into my projector and send only an audio signal from the blu ray player to my processor. I’d like to be able to do the same thing with my Nvidia Shield streaming device.
