Why won't my TV volume control adjust the volume of my external speakers?

Episode 936 (41:01)

Matthew from Columbia, MD

Leo says to try using the headphone out of the TV. The optical connection will work as well, but he needs to tell the TV in settings to control it. Some TV models don't support it, though, so it depends on the TV.

By default, most TV's only send line level when using HDMI or optical out because the manufacturer assumes that the user has an A/V receiver that they are adjusting the volume on.
