Product Research


Optical Digital-to-HDMI Adapter: If your TV does not have a HDMI ARC input, but does have an optical (toslink) digital output, this Optical digital-to-HDMI adapter can be used to get sound from your TV to a Sonos Amp, Sonos Beam, and other soundbars that only feature an HDMI ARC jack. This adapter will still support 5.1ch Dolby Digital and 2ch PCM.

Can this work with a PS4 because the PS4 hdmi is broken?
[ Charlotte  Dec 11, 2020 ]

This does not work to pass video. It connects to an optical port which is audio only. It will not work in place the the HDMI port. You will have to try to get it repaired. I wish I had different news for you there
[ Paul  Dec 22, 2020 ]  Staff
Is this adapter bi-directional? Can it be used to connect my surround receiver's hdmi output to another device's (DAC's) Optical Input?
[ Paul  Sep 13, 2020 ]
1 answer
Hi Paul. The Sonos Optical Audio adapter is not a bi-directional adapter, and would not work in your proposed application. Please chat with us online or by phone at 1-800-324-9695. We will be happy to go over your setup with you to possibly find another solution.

Can I remotely control my sound bar using my TV remote using Sonos optical audio adapter? I read you couldn't control the sound bar via a TV remote using only a optical connection, only able to using a hdmi cable. Will this converter allow me to control my sound bar using a TV remote?
[ FURY364  Aug 16, 2020 ]
1 answer
Yes, once you set up your TV to use the sound at you should be able to. However, I would suggest downloading the SONOS app to iPhone/Android and setting up and controlling it from there. I have 2 identical Sonos sound bars (one on an LG TV that required this optical, on a Samsung that didn't) and its a breeze to set up, configure and control from there.
[ H  Aug 16, 2020 ]
My optical audio digital output is broken and I can't insert my Sonos cord in to the tv. Is there a way to bypass this and use this device for sound?
[ Laura  Jan 29, 2020 ]

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ Calvin  Feb 28, 2020 ]  Staff
My tv doesn't have optical digital audio output. I'm looking at connecting a Sonos Playbar. Will this adapter do the trick? Thanks!
[ JeffJ  Nov 30, 2019 ]
2 answers
It should. I used mine to convert My sound bar. Now its a Sonos connected speaker.
[ Rashamon  Nov 30, 2019 ]
Hi Jeff, I am not familiar with the adaptor but it should work. If you would like to book an appointment with one of our specialist please feel free to contact us. Thankyou.
[ Digital Living  Nov 30, 2019 ]
Will this improve the Line in sound of a CD player(Integra cdc3.4)connected to the new Sonos Amp currently connected with the rca connection? In other words will it improve the sample/bit rate connection via rca in to the Sonos Amp seems to make for a loss of detail
[ Balooo2  Oct 10, 2019 ]

Hi Ty, thank you for your question! Unfortunately, using this HDMI to Optical Adapter wouldn't be your best course of action. However, adding a DAC, like the Cambridge Audio DacMagic 100 to your system would provide you with the improved sound quality, and make up for the loss of detail you are experiencing. Chat with us online or by phone at 1-800-324-9695, any of our amazing team of Advisors will be happy to go over your options!
[ Jess  Oct 24, 2019 ]  Staff
Can I use this to plug in my sonos soundbar optical output to an hdmi cable to my theater projector to get sonos operating with that?
[ Steve  Oct 06, 2019 ]
1 answer
Steve, I recommend you get in touch with one of our advisors for more in depth, personalized help. That way we can look more closely at your projector and the whole system.
[ Calvin  Oct 19, 2019 ]  Staff
Can this be used with a non-Sonos A/V receiver?
[ Justin  Sep 02, 2019 ]

This will work with non-Sonos equipmetn for audio transmission, yes.
