Sonos Ray connection using Optical to HDMI not connecting to TV

Hi,

I have a Sonos Ray and Samsung UE32F6000F, without optical port and have purchased the Sonos HDMI to Optical adapter.

I have switched the “eArc” setting on in the menu and connected the HDMI port to the one labelled eArc on the back of the TV.

I am unable to get the two to connect using the Sonos app and nor does the TV recognise a speaker has been connected.

I have noticed the optical cable end does not glow red when connected to any device (the TV, a laptop etc). I have also tried 3 other HDMI cables.

Any ideas/tips?

Thanks

Volume commands (anything CEC related) can’t be carried across optical, it just doesn’t have the bandwidth. You’ll need to set the audio settings on the TV, and anything that feeds it, to Dolby Digital, which is what optical can handle. In order to have your remote control the Sonos, you’ll need to set it to emit IR, then go through the process of ‘teaching’ the Sonos (in the controller) to recognize it.

Bleh, Amazon UK link….

Not familiar with this device (eSynic Professional 192khz ARC eARC Audio Extractor ARC HDMI to Optical Audio Extractor with HDMI & Optical Cable Support 5.0 and 2.0 Audio Format for HDTV to Soundbar(Must Connect TV eARC ARC Port))

Are there settings you can access? If such a device does work, it needs to be set to Dolby Digital, not anything higher, like Dolby Digital Plus or Atmos. This is the best that a Sonos Ray can process. 

Seems odd, in comparison to other devices that interpret eARC signal,  that it is so inexpensive. Have you reached out to that company’s CS for assistance? Do you have it powered?
