Hey Jean, thank you for that valuable info. I have tested the 18.08 version that you linked and unfortunately the pops at the beginning of audio clips still occur, but I have made an interesting discovery. When I render the entire project, there are three pops at the beginning of 3 clips, let's say at 01:23, 02:02 and 03:15 in the time line. These audio pops only come up in the rendered output, not during playback. When I only render a small selected zone surrounding the area where I know the pop will be, it does not occur. Only when I render the full project, they appear. I have tried this with all three known audio pops that I have spotted in the fully rendered project, and each time they disappear when I only render a selected area around them.
The next thing I have noticed is that switching the playback settings betwen SDL and RTAudio can affect this issue as well. As you know me now, I will now enter full testing mode and report back to you with a more detailed analysis. I will compile the latest melt, ffmpeg and co in order to provide a full report, but I will use the AppImage versio 18.8.0 which you have suggested. Anything else I should consider?
