Not exactly. It is my understanding that iTunes just sends the decoded content to the default output audio device, and this graph or however one has to call it then takes care of any resampling or conversion.

My approach is dead simple. Plugins receive a notification when a new file starts playing, and have access to properties like the content's sampling rate. This can be used to switch the hardware setting without audible artefacts (but with [potentially quite] audible benefits)). It's simply a software version of what one otherwise has to do by hand, using AMS ...

switching the h/w rate is ... if not exactly evil, then unfriendly. DP does this, and its bloody irritating to have it think that it owns the hardware when in fact other applications are using it at the existing rate.

if the rates do not match then either (1) ask the user what to do or (2) resample.
