How to hear tv audio output and setup box audio in Amplifier


Sep 9, 2017
I am using Sony Bravia TV, the channel setup-box RCA Cable audio output is connected to TV Audio input L&R & amplifier L&R by RCA Male to RCA Female Splitter, i can hear setup box audio in both TV speakers & amplifier speakers.
My TV has only one Audio output 3.5mm jack & when its connect to Amplifier through 3.5 mm Stereo Audio Male to 2 RCA Male Cable, then i hear only TV sound in amplifier speakers but not setup box audio.
i need to disconnect Audio output jack from TV to hear back setup box audio.
Is anyway to switch TV audio & setup-box audio without removing jack, because tv audio jack is backside everytime i need to tilt tv to unplug it
