How do I sync multi cam using a specific audio track

I have two recordings which I wish to sync. One recording is a camera shot and the other is a game recording. One of the game recording audio tracks has my computer microphone captured. I would like to sync the two clips using the specific audio track from my computer microphone and the camera clip which has its builtin microphone as FCPX could easily use this to sync using audio. I have not yet been able to identify how or if I can do this in FCPX.

Thank you in advance!

Try this: add a marker roughly in a place where the two should sync, and in the creation of the multicam check "on first marker". That could help.

EDIT: I meant to say one marker on each clip, of course.

I did this however the clip never gets synced due to the 5 other audio channels or because the software is not analyzing all audio channels.. I am not sure which. I need to be able to tell FCPX to use a specific audio channel to sync the clips. What happens when I do the normal selection and new multi-cam clips is it takes a while trying to analyze the audio and then winds up just starting both clips at the same point in the timeline.

This did it! I placed the marker on each clip where the sounds should sync (used a loud sound done for this purpose) and the sync took all of 1 second to get them synced! Awesome job! Thank you for your help!

Select the two clips in the browser, control-click and choose New Multicam Clip.

The default settings should suffice.
