Heres some information about ALSA hot plugging. Note that none of the scripts or procedures mentioned in the HowTo have ever been implemented in moOde. The only thing moOde does explicitly for USB audio is to regularly save the ALSA state when a USB audio device is configured. The "save" occurs during worker.php 3 second event loop, so every 3 secs.

Does Moode have any ability to power down USB ports after a period of inactivity, allowing the USB DACs to go into standby? Of course it would need to power the port back up prior to commencing playback...
