It is an the onkyo dsa2x dock, but I have no problems controlling the dock. I am not able to control the 605's zone 2 power, volume, or source selection. I have tried the IR codes from other onkyo receivers in the RTI IR database, but have had no luck. I just need to be able to select the zone 2 source, control the zone 2 volume, and then turn the zone off. Onkyo's site is no help with the IR codes.
