Why is playback stopping after a few seconds in the middle of the track and the plug-in reporting an error?
In general, playback issues result from a problem in the network. Several users have reported that the problem subsided after updating the drivers and firmware of their AirPort Express, network card and any other network devices involved. You may also try using a different AirPort channel if you are in an area with multiple overlapping wireless networks. If possible, stick with 54 Mbps (802.11g) wireless or 100 Mbps wired Ethernet. 11 Mbps (802.11b) wireless and 10 Mbps wired Ethernet may not consistently provide enough bandwidth for the audio stream. The Remote Speakers Ouptut Plug-In has higher bandwidth requirements than iTunes or Airfoil because it does not compress the audio stream before sending it to the remote speakers. This may explain why some users have experienced no trouble with those applications in the same network environment that causes problems for the plug-in. This deficiency may be addressed in a future version.
