I am trying to connect a 2024 Samsung 65” DU7100 Crystal UHD 4K HDR Smart TV, model number UE65DU7100KXXU to a SONOS Playbar.

The issue is the TV only has audio out via HDMI (ARC) but the SONOS Playbar only accepts sound in via an optical cable.

I assume I need a converter. However there are numerous options on Amazon or similar.

Can anyone recommend one that they use in same circumstances and definitely works ?

Thanks in anticipation.
