I programmed my Harmony 890 to use my Denon AVR-2809CI to control the volume in the Watch TV activity. While the audio is coming from the speakers connected to the Denon, there is no change when pressing the volume control on the remote.

Instead, pressing the volume controls on the remote results in the TV's on-screen volume bar displayed on my Sony XBR4 TV (as if the Harmony insist on controlling the volume through the TV speakers). The volume levels move up/down as if the volume is coming from my TV. Of course, with the Denon set to HDMI Audio Out / AMP, the only audio is through the Denon speakers.

Any help would be appreciated.
