This may not be news to some but I think others will find it helpful. I did not install the speakers on my new TV; all sound runs through my A/V receiver. The TV volume control does not affect the audio output to the receiver. I wanted to use my DISH remote to control the volume on the A/V receiver without having to switch between SAT and AUX mode. I finally found the solution in the 522 Remote Manual. The procedure works on my 722 remote:
SWITCHING BETWEEN TV AND DEVICE VOLUME CONTROL
When you set up the remote to control a TV, the MUTE and VOLUME buttons control the TV volume. However, if you want to use the AUX mode to control a tuner or amplifier and the device has a volume setting, you can set up the remote to control the device’s volume instead of the TV volume.
To set the remote to control the device’s volume:
1. Press and hold the AUX mode button for three seconds, and then let go of it. The AUX mode button will blink.
2. Press the POUND (#) button.
3. Press the plus (+) side of the VOLUME button.
4. Press the 0 number button.
5. Press the POUND (#) button. The AUX mode button flashes three times.
6. Press the SAT mode button.
7. Press the plus (+) and minus (-) sides of the VOLUME button. The device’s volume changes and the AUX mode button lights instead of the TV mode button.
To set the remote back to control the TV volume:
1. Press and hold the TV mode button for three seconds, and then let go of it. The TV mode button will blink.
2. Press the POUND (#) button.
3. Press the plus (+) side of the VOLUME button.
4. Press the 0 number button.
5. Press the POUND (#) button. The TV mode button flashes three times.
6. Press the SAT mode button.
7. Press the plus (+) and minus (-) sides of the VOLUME button. The TV’s volume changes and the TV mode button lights instead of the AUX mode button.
