How can I make VLC output its sound through USB headphones? Whenever I plug-in my earphones with a round connection into my MacBook Pro, the sound automatically switches to them. Whenever I plug my headphones with a USB connection (Logitech USB ClearChat Comfort Headset) and I am playing sound in iTunes, the sound automatically switches. Whenever I plug in my headphones and VLC is playing, the sound continues to play through the speakers. Is there any way to make VLC work with my USB headphones?

Update: It seems that the headphones don't work properly with Skype either.
VLC can't switch audio interfaces on-the-fly. You either have to stop playing media entirely, and go into the preferences and change it, then start playing your media again; or, the slightly easier way:


Kill VLC
Plug in headphones (and ensure they become the primary output sound device, hold option and click the sound icon in your menu bar, select usb headphones if necessary)
Start VLC


Assuming VLCs preferences are still set to use the Default Audio Device for output, then it'll use them when you start playing content again.
