V18 after creating 4 camera multicam track no audio plays. Audio wave form is there, & of course, the 4 cams in the multicamera track, whcih work as expected. I imported a mixed version of the audio and it won't play. With a previous project I verified V16 pro works as Vegas always has until today.(I go back before Sony). Help. This is not a sync problem, etc. I've been using Vegas for multicam for more than 20 years. This has me boggled. HELP!! If I could I'd migrate this 1 hour video back to V16 (I skipped V17). REPEAT: with another project, I verified V16 works as expected: Create a multicamer track out of an edited 4 camera shoot and you have a multicam track and the audio from the shoot into one track, and you can add a mixed audio track, etc. I hope I'm just missing something that is easy to fix, but right now I'm stuck. Thanks. I'll gladly pay for help today. Deadline. Mark Removed by Moderator
