Ubuntu 10.10 with kdenlive installed using the repository from ppa sunab.
If I use the volume effect to decrease the audio level, putting it for example at 50 it works ok in the preview but when I export the video the audio is just muted.
Indeed if I increase the volume effect when I export I can hear the difference but it is minor than in the preview.
Changing the export codec does not make any difference.
Any suggestion are really welcome, this is the only problem I have with kdenlive but it is very annoying!!
