It's been asked many times. And here's a recent post about it.

I used a Klipch 2.1 sound system with my old Sony. The TV could be configured to shut off the TV speakers and have the TV volume control set the volume on the 2.1 speakers.
This does not seem to be possible on the HU9000. The audio out jack has a fixed output not controlled by the TV volume so I must adjust the 2.1 system volume manually by turning a knob on one of the speakers. This is unacceptable as I want to use the TV remote for volume control and mute.
Perhaps a software update can fix this problem if Samsung can do that. I'd rather not have to buy a soundbar.
Any other solutions?? Thanks for your help.
