Phantoms and Dialog in limbo

[Bbnsound]

I usually don't use Spark either; most of the times I use iTunes via Airplay (when not actively listening music).
However, there is still this annoying crackling issue and the customer support told me, it is due to a faulty Airplay protocol which can only be resolved by a Spark update.
So, although I don't use the application I would substantially benefit from an update of it. Like this I can't fully use the advertised Airplay compatibility and hence, the speakers are far from producing "the best sound of the world" with Airplay.
