Arun, I just tried with load-module module-suspend-on-idle timeout=0, and it seems to work fine on the HDAudio output. I was able to switch back and forth between 44.1 and 48kHz tracks without audible issues. I am not sure what happens with Rhythmbox if you enabled the cross-fade between tracks, most likely you would remain at the rate defined by the first song. -Pierre
