Is it possible to program the CLIKR-5 (UR5U-8780L) so that while in CBL mode the volume/muting controls use the AUX device (as opposed to TV)?
If not, does Spectrum provide a remote that allows this? I used to have an old SA remote (AT8550) that allowed this. It is very useful for running audio through a home theatre device.
I see an AT8560 listed, maybe that's a possibility?
There should be a 9xx comand that allows you to lock or unlock buttons from a device. Problem is that the device must be accessable thru the remote.... If you can't assign it to the aux button, you're out of luck.
What light comes on when you press aux then volume up?
Well, per the instructions, when I hit AUX and then volume up, it changes the volume on the AUX device. This is workable, just not convenient since I have to keep switching between AUX (for volume/muting) and CBL (for channels/guide) modes. Wife doesn't quite get modal operations!
These instructions only talk about moving volume controls in CBL mode from the TV (default) to the cable box.
The old manual talks about the 993 command to assign volume control... perhaps it's worth a try...
There is a method! I've posted the steps here, but the programming steps can also be found in the manual that came with the remote, or online at https://www.timewarnercable.com/en/support/program-your-remote/UR5U-8780L.html
To set the volume control to the AUX button, use the following steps:
1) Press the [OK/SEL] button and [CBL] button simultaneously for three seconds. The [CBL] button will light up and stay lit up for 30 seconds. The next step must be performed while the button is lit up.
2) Press the [VOL +] (volume up) button one time. The [CBL] button will blink.
3) Press [AUX] button once. The [CBL] button will blink twice to confirm the programming.
And there you go! From now on, the volume controls will override to AUX instead. There is a small drawback I would like to warn you about though. As you described in your post, you normally press AUX and then VOL when you want to use AUX instead of TV for the volume, right? When programmed to AUX, this same method does not work in reverse. If, for any reason, you need to change the TV volume instead, you will need to press VCR instead - it will still auto-direct to the TV volume.
