I exported the soundfile from my shotcut project and edited it in audacity, then I exported it from audacity (into a monofile, no other option for WAV) and brought it back into shotcut. But there is no sound. I can see the meter but I can’t hear anything. Same thing with mp3, and with AIFF. The tracks are not muted. No mute filter. I also tried some other wav file which came from some former shotcut project, same problem. I tried another mp3 file from some other place and it worked.
If I double click the file in the playlist there is no sound and if I drag it into an auditrack in the timeline there is no sound.
