Question Using TV as a bluetooth speaker

Mar 19, 2023
Hi there,

Sorry if this is a duplicate but i couldn't find a question like this.

So i currently have this samsung TV UA55RU7100WXXY

I wish to use it as a Bluetooth speaker, so I thought to use a receiver like this

Which can convert a Bluetooth input signal to 3.5mm AUX audio output, but the problem is my TV has no AUX input.
I then purchased a 3.5mm female to 2 RCA male cable to plug into the back of the TV, into the Component/AV input but the TV wont detect any source (i assume because there is no video input)

I guess i am wondering has anyone else tried this specific use case? And if so, how did they approach turning their TV into a Bluetooth speaker?
(Maybe i should be trying to use the HDMI input instead of and Component/AV input? If so, is there a hdmi adapter that takes no video but audio?)
