This version of premier seems to have a lot of audio bugs. These are the ones I’ve encountered (in my first week of use)
1) messages that tell me that audio files have gone missing (these messages go pretty quick)
2) audio issues cause playback to stop with multicam.
3) Glitch sounds all over the place
4) Beeping sounds on my exports (in the same place where the glitch sounds are)
5) tracks muting/un-muting when I hit play
Sound is often an after-thought for many video folks. I’m guessing it was an after thought for adobe when they were bug testing as well. I love how feature rich this version of Premier is but they ruin it all when I can’t rely on the absolute basics like pressing the spacebar to play or exporting a video on time for delivery.
