In my TV there is input and output jack also available but the audio of av is not play on home theatre

Solution
I assume you plugged your audio cable into the output jack.

Check the TV menu for audio options. Make sure the output is on. If there is an option for that.

On your stereo make sure it is set to the correct source. Also if multiple input jacks go to the same source option. Switch input types. For instance on mine. If I select DVD. I then have options for optical, coax and RCA.
