Well, whether Qt is the best choice is debatable, and it's one of the most common recurring debates we have in these parts. So no need to rehash that stuff.
Now, if we're talking about cross-platform sound, then one could argue that SDL is a good choice. It works on more platforms than basically anything else (there is even an iPhone port, that only awaits Apple's blessing).

Don't forget PortAudio. If you're going to judge a tree by its fruits, Audacity is a working application on the Microsoft, Apple, and Linux platforms (good enough that mic manufacturers can put a copy in a box with a USB mic and call it COMPLETE PODCASTING KIT) and it uses PortAudio.
