So, I plugged in a usb drive with some music on it to the one AA I have, and would like to play the music on another one as well as the one that is playing it. I thought there were ways to select which speaker plays what?? At least my understanding of the AA was that through the WebUI, I could select what plays, and which AA it plays on. This seems to not be the case unless I'm missing something. Any ideas? Thanks.
