I am looking to purchase a ceiling mounted 4K projector. The video from a few different sources will be output to the projector via a single HDMI cable, while the audio needs to be output to my Sonos Playbar and from there disseminated to my two Sonos PlayOne rears and a Sub.
I assume I need to purchase an AV receiver with the following inputs:
-Apple TV (HDMI)
-CD player (RCA)
-Rooftop antenna (COAX)**
**My understanding is I will need to pass the antenna signal through a separate analog-to-digital converter before connecting to the receiver.
My question is: how best to get the audio signal from the receiver to the Sonos? Most affordable receivers don’t come with digital audio (optical) outputs, so do I need to use RCA (analog) cables to carry the signal from the receiver to a Sonos Connect, and from there an optical cable to go to the Playbar? If that’s the case, will the sound quality be significantly impaired by the analog leg of the route?
Or could I forego the receiver altogether and use an HDMI switcher instead? There are several switchers with optical outputs that could connect directly to the Playbar. That said, I haven’t come across any HDMI switchers with RCA inputs for my turntable and CD player.
Unfortunately I’m not particularly tech savvy, so I may be missing the obvious way to do this; any guidance would be much appreciated!
