Hello. My question is about the possibility to connect the optical input of my Playbar to the hdmi arc output of my TV through the sonos adapter. 
it’s clear form thec spec that the adapter is to connect optical on tv to hdmi on new sonos products, but I would know if is possible the opposite (connect optical on sonos playbar to hdmi arc on tv). Thank’s a lot 

See this older thread which suggests that it doesn’t work…

Ok, thanks per the feedback.

Any suggestion for a reliable and performer hardware to solve the problem?

Best Regards


This is the only device I’ve heard of that can convert an ARC/eARC signal  to optical output.  Never used it myself, but have heard that it works reliably.
