Description Unknown 2016-07-19 05:42:46 UTC

When I added a clip (.mkv) into the Project Bin, I noticed that the audio meter changed to a series of lines on the Clip Monitor. No indication of audio activity during playback. Project monitor audio monitor, however, works fine.

Reproducible: Always

Steps to Reproduce:
1. Create  new project (HD 1080p, 24fps)
2. Add clip (.mkv, 1904x800, 23.976fps)
3. Have selected and look at Clip Monitor and/or playback clip in Clip Monitor.

Actual Results:  
Audio Monitor is showing as a series of grey horizontal bars.

Expected Results:  
Audio Monitor should work like normal.

Bug discovered while using Kdenlive git master build via ppa:kdenlive/kdenlive-master.

Not sure if it helps, but there're a lot of these in the Terminal when running Kdenlive and trying to play back the .mkv file in question:

I guess the video has  5:1 audio.. Can you paste the output of :
ffmpeg -i youclip.mkv

Comment 5 Jean-Baptiste Mardelle 2016-07-19 06:49:54 UTC

Ok, I can reproduce with a 5.1 audio clip, will look into it
