My setup is for TV surround sound. A SONOS Play Base connected to a TV, via optical cable with a SONOS Sub and two SONOS Play 5s and all was working fine until my TV broke.

I bought a new Samsung TV (Samsung QLED QEF1 4K), but it doesn't support optical output. Most of the new TVs available don't seem to support optical output, and I know the SONOS Play Base only accepts optical input.

The TV has HDMI ARC, so I tried to find a solution - HDMI ARC output from TV to Optical input to Play Base, with a converter of some sort. 

When I contacted SONOS support, they told me no such solution exists and to buy either a new, different TV or a new SONOS sound bar product.

ANY OTHER SUGGESTIONS PLEASE??

Yes I know there is a  Optical Audio Adapter | Sonos : from SONOS, but this only does Optical to HDMI ARC, not the other way around.

Thanks for any help - Stephen
