Logic: Output video sound to external card

Hi everyone!

I am currently recording some music for a movie I made. I imported the movie into Logic Pro 9.1.7 and am absolutely stunned by the quality of the sound library (I have mainly used it so far to record analog signals from mics...)!

I only have one problem I can not seem to fix: I record and play back every track on an external sound card with MIDI (obviously...). But the sound track of the imported movie is only played back via my internal speakers. That's obviously not what I want and I would love to have everything mixed on my external card.

Is there a simple way to do this that I am just overlooking here?

Thanks a lot!

PS: Although I am quite good with instruments and have had Logic for 3 years now, I don't have a lot of experience with it. I mainly mixed and mastered a 5 part a cappella group, which was a blast, but not that difficult.

 

Hm. I honestly don't know what went wrong until now. I did nothing but start another application (iTunes) and listened to a track on the external card. And now the movie sound plays back perfectly and mixed with the music, just like I wanted it to.

Sorry to bother all of you. What I did (in case anyone ever reads this thread in the future):
- in MacOS's "Audio-Midi-Setup", I changed the default output to the external card
- I started Logic
- In the Logic Audio Preferences, I put in my external card as In- and Output
- In the Project Video Preferences, I turned up the movie audio volume
- I switched to iTunes, played back one song and switched back...

Thanks anyways!
