it is not very clear what you want, if you want to listen to the tv on the amplifier, whether your amplifier has hdmi input or not, or not explain well. look there are different devices in the market for what you want, like an hdmi converter with hdmi and rca output so you could send the audio signal to the amplifier, an example the following. device, everything is question that you approach the electronics store, you can also remove the audio from the TV with another device from the internal horn cables, but this can only be done by a technician .... greetings.
