[vlc-devel] Re: [MOD] Mac OSX multichannel patch

[Derk-Jan Hartman]

I think the audio device is a dynamic menu.... though i'm not really 
sure. So as soon as you edit the vars etc, the menu should update as 
well. (if not, then it should be changed to do so :)

And no, the refresh callback system isn't working on OSX. But that's 
only for preferences anyway, and this defnietly doesn't need to be 
implemented as a preference, rather as a variable system.
