Unfortunately there’s not. Anyone else got a clue?
Double-check you’ve got “search for shared libraries” enabled in your itunes preferences.
What version of firefly do you have? Does it show the loaded modules in the web status page? Does it show rsp and out-daap loaded?
Did you upgrade from the stable (0.2.4) version? And if so, did you let the ipkg overwrite the existing config? If not, try re-installing (with –force if necessary) and let it overwrite the config, then edit it to taste.
Failing all that… are the client and server separated by wireless? Does your wireless router have any configuration to enable IGMP or multicast (or even maybe upnp)?
The config missing the entries to load the plugins and the wireless dropping multicast are the most reasonable things I can think of that might be wrong. More info on how the network is set up (link types, router brands, etc) and info on the version might be helpful if these ideas don’t pan out.
