Tutorial On Audio Mixing / VS Pro X9

[DayO]

Where is there a good tutorial on audio mixing in VS Pro X9?

I have a sound effects track I want to mix with an already-existing audio track.

I applied the sound-effects track to the Voice Track, but I can't adjust the volume on the video clip to
the point where it's mute.

Is this a case of Audio Ducking?

Have you tried just muting the audio on the clip - - Right click on the clip in the timeline and choose 'Mute' from the pop-up

No, will try that.

Thanks.
