That's true for embedded audioClips, but for cases where QuickTime files 
can be an option the future looks more promising:

If I recall correctly from Trevor's notes in an enhancement request some 
time ago, QT provides APIs or that but LC is still using an older method 
of initializing QT structures that prevents using some of the newer APIs.

I believe this will be addressed (along with a great many QT-independent 
issues with media playback on Win and Linux) as part of the "Multimedia 
engine" rewrite among the Kickstarter stretch goals, on the roadmap 
under Queued as "Multimedia":
