I have a Pioneer Receiver SC-81 connected to Samsung 8000. My issue is the volume when watching straight cable channels (Comcast) is very low. When you switch to smart hub, DVD, or radio the volume is extremely high. In order to watch cable channels you need to turn the volume up much louder than the others. I assume each is connected through a separate HDMI. I didn’t do the setup and these days not to into the technology to rectify this issue. Rather frustrating when the kids switch from one to the next and the volume goes through the roof. Please help
