Play CD from CD player attached to Beam via HDMI-optical adapter

I have a SONY 5 CD player with optical out. I connected it to my Sonos Beam with the HDMI Sonos adapter. When I play a CD on the SONY no sound comes out of the Sonos. What else do I need to do? Thank you

When I tried again after removing and reinserting the optical HDMI hybrid cable, I got a message in the Sonos app that “there is a problem with the HDMI cable but we can fix it”, when I clicked on that, I was told to reinsert the HDMI cable into my TV’s HDMI-ARC port.

So the Sonos app only recognizes the output  from my TV via its HDMI-ARC connection.

I need to find out how to make it recognize the HDMI-optical cable CD player connection.

I called Sonos support but they are not open today, so I will try again tomorrow and post any solution here,

First thing I would do, is switch your TV output to use its optical port and check that the Beam HDMI cable, coupled to the optical adapter, is working with the TV - if it works, then you will have narrowed the issue down to your CD Player.
 

Of course, if you do have access to another receiver/amp with optical-in and speakers (or headphones) you can perhaps also test the CD Player optical output is actually working.

Problem is my TV does not have an optical audio out (it is an LG OLED TV).

For the TV I use an HDMI ARC cable connected to the Beam.

I disconnect this when I try to play CDs via the Beam and use the Sonos optical adapter.

I have the LG C9 OLED and that has optical - are you sure? 
 

It’s extremely unusual for LG, or any TV manufacturer, not to include an optical port, what model is it?

That TV model does have an optical port and you should see the port on the rear of the TV with the option to switch to it in the WebOS TV under "Settings/Sound/Sound Out” - it’s the 2nd entry in the list after ‘Internal TV Speaker’. So you could use that port output to check the cable and optical adapter are working okay.

I have the same/similar TV and I’ve just set my TV audio out port to pass-through the audio and I put a music CD in my PlayStation and that plays the CD-DA (red book) format okay on the Sonos Arc, so I would guess it will work for the Sonos Beam over optical too.

I would check the cable/optical adapter first, using the TV optical-out port and then take it from there… it might be that the CD player needs to somehow switch its own output to its optical port, presumably that might be on your CD ‘remote’, or perhaps the player itself?

    Thanks,I’ll pull the TV out tomorrow and check for the optical out port, then try to attach the cdmi-optical adapter and see if I can send the tV output to the Beam that way, thereby verifying the cable.

     

    There is nothing in the CD player manual or remote about verifying or selecting the output. The player just plays through whatever output has a cable.

    thanks for continued help
