Here's my setup:

I have a MacMini housing all of my iTunes music, which streams to various stereos throughout my mouse via Airport Expresses.

The setup works great, but I'm now trying to get my RF Harmony remote to be able to control the WiFi output volume.

Using the Apple remote and learning it's commands on the Harmony) I can control the "previous track" and "next track" functions, but can't seem to get the volume to change.

It looks like the Apple remote will only control the output volume to the computer, but does nothing to output volume streaming via WiFi.

I'm guessing I am out of luck trying for volume control with this setup, but thought I'd see if anyone has been able to do this.

Thanks.
