I have a flat screen tv with av/component out port for video and sound. I would like to know if the volume control on the tv controls the volume from this port or not. Thanks for any help.
If you take that output and plug it into a reciever or somethign for surround sound. No. The reciever remote will control the volume. Only the remote for the TV will control the volume comign from the TV not any other device.
Unless of course you have a multi functional remote that you can program to control other devices and have that remote control the reciever as well.
