I called support after trying to set my remote to control cable volume on the new DVR. A little light blinked on the box when I push a volume button but volume bar didn't appear on screen. First support call tried to match my remote to TV, and I finally got him to realize that's not what I was trying to do. He said remote was defective, sending a new one. I called back because of no caller ID (told I have to wait a day), and I mentioned the volume problem. She said I can't control volume on the new DVR. After hanging up I was looking through the setup menu, and I discovered a setting where THE CABLE VOLUME WAS TURNED OFF! I turned it on and it works. Two different support people didn't know about that.
Solved! Go to Solution.
Most everything has an audio option.
Fixed sends full audio out to tv& stereo systems to be controlled by their own volume controls.
Variable uses the cable bax remote to vary it's output level.
Depending if you have dvd/blu ray players, sound bars hooked to the TV, there can be different ways of setting these up.
