Are you sure it is connected via an HDMI cable?  The HDMI connection used on Sonos soundbars is HDMI-ARC, which is usually only available on TV’s and specialty adapters.  I know of no DVD/Blu-Ray, never mind CD players, that support HDMI-ARC. 

Could you be referring to an optical connection?  These are used by the Sonos Playbar, Playbase, and Ray or an Arc/Beam with the Sonos adapter.

You can’t just connect the CD Player to a spare HDMI port on your television?

Mr. T

I connected my cd player to an HDMI cable via an adapter.  When I plug that HDMI cable directly imy Sonos soundbar, it works perfectly.  I tried connecting it to my TV, but it does not work.  TV says “no signal” possibly (probably?) because it is not getting a video signal.

 I connected my cd player to an HDMI cable via an RCA output adapter.  When I plug that HDMI cable directly into my Sonos soundbar, it works perfectly.  My TV connects with my soundbar directly via HDMI cable.  What I need is a switch that will accept both inputs and let me choose which one goes to the soundbar.

Well, whatever works. Any 2-into-1 HDMI switch, manual or remote, will probably be sufficient.  THere are hundreds of them out there.

What converter/adapter are you using? I suppose it must be converting the stereo signal to an ARC signal, otherwise the ARC(HDMI) input wouldn’t be accepting sound. 

Which Sonos soundbar are you using? 

There are, to my knowledge, very few ARC switches available. You may want to look at HDFury, Feintech, or OREI. There may be others now, but it is an extremely small market, or has historically been so, that may be changing.

If you read my post, you will see that I asked for replies from someone who could “ offer some advice, based on their own experience with this issue.”  While I appreciate your interest, this is obviously NOT you. The comment that “Any 2-into-1 HDMI switch, manual or remote, will probably be sufficient.  There are hundreds of them out there.’” is partly correct. that are ‘hundreds out there”  Unfortunately an ordinary switch won’t work!  Trust me; my remarks are based on experience. Not idle conjecture.  The reply from :Airgetlam: above shows some understanding of the problem and a possible solution.

I believe you are correct.  Since this units are expensive, I was hoping that I would get a reply from someone who was actually using one of these.  

Thank you

Doc

While I’ve used both the OREI and the HDFury, they were both in a singular interface, between my output of a DirectTV box, and the incapabilities of my TVs to handle eARC. I am not familiar with the multiple input aspects of some of these devices, I’ve not used / investigated them.

I note you avoided answering any of the questions I asked, which might potentially help other people assist you more concretely.

Sorry.  The information you asked for is below.

I am using an AV2 HDMI Converter which I got from Amazon for $10.  It takes RCA jacks on the input side, and outputs to an HDMI cable (This output works fine when I plug it into the input on my sound bar).

The soundbar I have is the Sonos Arc

Odd, I see absolutely no reason why this system, which doesn’t appear to convert a signal from RCA to ARC, should work, when plugged directly into the Sonos Arc. It would make more sense to me if the HDMI input from this device were plugged in to the TV set, and then the Sonos Arc was plugged in to the TV’s ARC port.

I’m delighted it’s functioning for you, it certainly is significantly less expensive than a typical eARC generating device, such as the ones I mentioned. However, as it’s working for you, ​@jgatie is absolutely correct, any HDMI switches available should work, as long as they pass ARC content, which is how your TV communicates with the Sonos Arc with any content from a HDMI input. 
 

I’m curious to know what TV model and that of the CD player. For future reference (not just for this forum) it is always helpful to describe the equipment involved. For example:

• TV = LG C5 model LGXXXXXX
• CD player = Sony ES Model XXXXXX

I tried three of the many switches available from Amazon. One from an unknown Chinese brand, one from Anker (also make in China) and one at the link below (copy and paste in browser, if interested) ,  This was a more complex unit, which looked promising, but didn't work for me. It came with an unreadable manual: a web search for more information was not helpful.  I think that if I had been able to configure the device it MAY have done the job.-insturctions (such as they were) hinted at that. However, I was unable to reconfigure, possibly because the device was defective,  (No way of knowing)

4K@60Hz HDMI Matrix Switch 4X2 with ARC, avedio links 4 in 2 Out Matrix HDMI Video Switcher Splitter + Optical & 3.5mm Stereo Audio, Scaler 4K 1080P Synch, HDM I Audio Extractor with IR Remote Control.

All three devices passed the output from my CD player to my ARC soundbar.  All three devices did NOT pass the audio portion of my TV set to my sound bar.  

Doc

It seems like the devices transfer regular HDMI audio to the e-ARC audio output pins, but ignore e-ARC input to the switch.

​@Macnooder 

I asked for the model info for your TV and CD player in a previous post. Are you unable to provide that information?

Ajtrek

My TV is a 3 year old LG smart TV

My DVD player is a 20+ year old Onyko

Finding exact model numbers is a chore involving shifting furniture and scrounging around in cabinets.  If you will tell me what use this information is to you, and (more importantly) how it relates to my problem, I will happily dig it up for you.

Doc

Just a possibility….not guaranteed and it may cost you very little or nothing 

• If you TV has an RCA input or Optical in-put 
• If your DVD/CD player has RCA or Optical Out-put

You may be able to connect one of the DVD/CD player out-puts to the corresponding input on your TV. Then using your TV’s remote select that output when you want to use your DVD/CD player for music. The audio should play through Arc via it’s HDMI connection to your TV. No switch required.

I did try sending the CD player’s HDMI output to an HDMI input on the TV, but the TV just gave me the message “no signal”.  My TV has only HDMI and USB inputs

OK…

• Was the CD player turned on and playing?
• Did you (using your TV remote) select the HDMI input for the CD player?
• Did you check the HDMI connection between the TV and the Arc (there should have been no switch involved)?

All the above should be answered as “yes”. If not correct the offending requirement. If still no luck then there’s something else afoot.

Duh

Well, I see you don’t need my help/suggestions. So good luck to resolve your issue! Goodbye !!

Comes to ask for help, then insults and offends all those those who try to help. 

Welp folks, we tried.
