I spoke too soon ...yes, now when I press the aux button, it will control the volume on the HT, but when I try to program the same keys on the "cable" button (so I don't have to switch to aux everytime I want to adjust the volume), it won't take. I go through the same procedures, but it will not work with the cable volume buttons. The light blinks twice and it looks like it will work, but no dice.
