Echo Dots can also be connected to your soundbar through an AUX (3.5mm) cable. This is because Dots are equipped with an AUX output port, and most soundbars have an AUX input. This is an easy, wired connection that is possible with a soundbar, as long as your soundbar and Dot are near one another (or you have a long AUX cable).
Here’s how to make your wired connection through an AUX cable:
Get a 3.5mm AUX cord. Make sure it is a good length
Open up your Amazon Alexa app on your smartphone
Select ‘Devices’ from the Main Menu Settings
Select your Dot by its name
Select ‘AUX Audio’, then ‘Line In or Line Out’
Connect your AUX cord to your Echo and your soundbar
Now you are connected through your AUX (3.5mm) cord, and any streaming or listening on your Echo Dot will come through your soundbar as long as both are powered on. If you ever want to listen to your Echo Dot through another device, simply disconnect the AUX cable from your soundbar.

PCM mode is a digital audio file that should be sent to the soundbar via an optical or coaxial digital audio cable. The coaxial digital audio cable uses an RCA plug but not the L/R stereo channels of analog audio. The aux input is usually the 3.5 MM cable from a computer, CD or MP3 player or a cell phone or tablet.

First, which type of RCA cable is connected between the sound bar and the TV? Second, are you sure that the TV connection is an audio out? (A number of recent TVs have only one audio output. This means there is only the optical audio out and not even a headphone jack.)

Once you double-check the input at the sound bar, choose the Line In input if you are using the stereo RCA cable. If you are using the Optical input, select that input. Use either the Mode button or the specific input button on the remote. Then double-check that the TV is set for the appropriate audio out.

I hope this helps. Please add a comment with the model of the TV and the sound bar for further information. I looked at the ONB18SB001 documentation for some of this. The manual for this Onn soundbar is available at Manuals Lib. See https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=12#manual for the list of input modes and the input to which they correspond. Here is the image of the inputs on the back of the ONB18SB001: https://www.manualslib.com/manual/1498038/Onn-Onb18sb001.html?page=7#manual .

Look for an audio output jack on the TV. You may have to adapt the cable from the soundbar to the jack type on the TV.

Please get a optical cable and run it from TV to soundbar for best sound. If you are using aux input on sound bar that will work but it is analog sound. TV needs to have mini audio out or red/white output on it maybe labeled audio out

If you are connecting the soundbar to your TV with the digital audio cable, make sure to select "D IN" using the source button on the soundbar. Bluetooth (BT) is a separate source from another device. (phone, etc.) The TV will need to be set to use the digital audio output and probably PCM format. (?) The subwoofer is preconfigured at the factory to mate up with your soundbar. (See below instructions - your soundbar includes the amplifier:)

Digital audio output setting:
After connecting an amplifier with digital audio input and
external speakers as shown, you should set an audio
output format compatible with the programme you are
watching or the device connected.
Go to "HOME" > "TV Menu" > "Setup" > "Option" >
"Terminal setting" > "Digital audio output" > select
"PCM" or "Bitstream".
NOTE
• When set to "Bitstream", Dolby Digital is output when the Dolby
Digital or Dolby Digital Plus audio formats are received. When
set to "PCM", PCM is output no matter what audio formats are
received.
• When set to "Bitstream", HE-AAC audio formats can be output
as Dolby Digital.

Does your TV have a Digital optical port? It's a cable that sends a red light source. That is actually how you're suppose to hook up a soundbar. digital optical cable Bing images Straight forward. Plug and play. If you're TV doesn't have an optical port, as I know your soundbar does then you have to use a stereo Y Cable. 3.5mm to Red/White. Sound bar will have 33% the power going this way as opposed to an optical cable. Aux Audio Out has a itty bitty amp pushing power. Purpose of the Digital optical Cable is a light source.

hook the soundbar to your axillary output or audio output or speaker output

Are you sure that jack is the output jack?
