Sonos Purchase - ETA late Dec/early Jan - "5.1.2 Surround Set (2 x One) with ARC + Sub (Gen3)"
Projector: Optoma GT1090HDR with HDMI Inputs - 1 x v2.0 4K, 1 x 1.4
Sound Output from Projector - L/R (Red/White) RCA jacks only - I would think I do not want to use these.
Various devices for Source:
-Sony 3D Blueray Player - BDP-S5200 - hdmi output with "orange" Digital Out Coaxial
-Apple 4K TV - hdmi output only - Bluetooth for audio??
-Roku Ultra - hdmi output only - not sure if options for other audio.
-Dish Network Joey - hdmi output - L/R RCA Jacks and Optical
-PC with RTX 2080ti - hdmi output - optical from Motherboard
-PC with RTX 3080ti - hdmi output - sound card orange/black/green 3.5mm jacks
I'm assuming, 99% sure, all of the sources above I can get my audio via hdmi.
What kind of hub do I need, for the 6 different sources, to extract the audio from the hdmi signal, sending the video to the projector, and then sending the audio out (via optical?) to the ARC? I know nothing about Bluetooth. Is there a hub that extracts audio from the hdmi signal/source, and transmits to the ARC? Will optical/spdif give me signal needed to give me the surround?
Even if the "device" to get audio to the ARC only accepted 1 hdmi input, as obviously only going to be using 1 source at a time, that would be fine.
I see in another post, a Pass Through device. VAX0401, but I can't seem to find in the U.S. I live in Arizona. Is that what I'm looking for? A passthrough device with audio out?
Something like this?
Any help or direction would be appreciated.
Thank you :-)
Edit: - Hmmm. After doing a bunch more quick reading, it seems “splitting” the sound off of hdmi will create a delay in the audio, as some call “lip sync issues”. That makes sense. After thinking about this some more, it seems the video and audio must come simultaneously from the source to the receiving devices (video/audio) to eliminate video/audio signal delay. Is that correct?
