Question LG Smart TV no sound after connecting bluetooth transmitter

Jul 28, 2019
Hi All,

I have an LG smart TV model # 43LJ554T-TA

I got a Wzatco Bluetooth transmitter connected to RCA white and red plugs. No sound came. Then read a thread here that those are actually input plugs in this tv . So i bought a digital optical coaxial box which converts digital output to analog. Plugged this converter using Toslink cable to TV's digital output and other end goes to spdif input in the converter. Then again connected Bluetooth transmitter back to RCA white and red plugs

Still not working. I know bluetooth transmitter is connected to my bluetooth headphones. I changed TV sound to PCM digital out as well.

Can someone help what am i doing wrong here?
