HDMI Arc Playback

i currently own 1 Sonos AMP that will power my Sonance MAG 6.1 outdoor setup for the pool area & will buy another AMP to power (2) Klipsch AW-650’s that will be for the Patio area. I will also buy the Sonos Port to control my Onkyo 686 amp that is powering my home theater setup.

I do plan on bringing a spare 43in Samsung TV out in the patio/pool area that i will want the audio from the TV to be playing from the Sonos Amps.

The question I have is, IF i run an HDMI from the TV (via ARC) to lets say… the AMP that powers the patio speakers… can i have the audio from the TV going through the other Sonos components ?

If so, will there be audio delay/lip sync issues ?

Yes, and yes. There would not be any appreciable delay on the speakers connected to the Amp, which you’re feeding the ARC signal to, but as soon as you extend that data to other Sonos ‘rooms’, the signal will need to be buffered, and the other ‘rooms’ would be at least 75ms behind the Amp’s ‘room’.

I’m not aware of an HDMI matrix switch that handles ARC or eARC in a useful manor. The ARC or eARC concept is that a dedicated client device will handle the audio, not that the audio will be distributed to multiple devices. Along with audio and video the ARC or eARC shares CEC (Consumer Electronics Control) information. This allows the user to simply drop a disc into a player, select a TV App or turn ON the cable box and all of the system components switch ON and to the proper input. This is intended to be plug’n play for the consumer. It’s not quite plug’n play when attempting to push CEC through an HDMI matrix.

Another complication is that ARC or eARC audio uses a different set of pins from regular HDMI audio. The HDMI matrix would need to be aware of which audio you want to use. All of this could be handled with a separate control processor, but this is not quite plug’n play.

I wasn’t suggesting that a matrix would handle ARC/eARC or CEC. Perhaps I didn’t say it clearly, but my setup has the matrix between source(s) and TVs, not between TVs and audio equipment. The ARC/eARC connection between TV and Sonos Arc/Sonos Amp are still in place like normal.
