Hi
I recently updated to the newest version after a few years of not updating. As mentioned in the title, the waveform visual on some audio files (whether separate or attached to a video file) is darker in brightness compared to others. Those darker ones don't play audio at all (video still plays fine) when on the sequence but do play audio when the clip is viewed on its own.
Here's a screenshot. The top audio is the one that's not playing while the bottom one plays fine.
