Bug ID: 417868
Summary: Specific WAV files not played when seeking / out of
sync when cut into several parts
Product: kdenlive
Version: 19.12.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export

WAV flle triggering the issue.
SUMMARY
After recording a WAV file from my phone (LineageOS Android / "Soundrecorder")
I and inserting it into the Kdenlive timeline, I noticed the file would only be
played when the "time" cursor is first set before the beginning of the audio
file in the timeline.
If I seek / start playing the video preview after the beginning of the
aforementioned WAV file, I hear no audio. If I cut the audio file (inside of
kdenlive) into several pieces, each piece is played at a bad offset relatively
to the full WAV file.
After double checking with other WAV files, I figured out it would only happen
with WAV files produced by the Android Soundrecorder. They don't seem to be
corrupt though, I can open them in Audacity etc.
STEPS TO REPRODUCE
1. Record a WAV file from the Android Soundrecorder
2. Import it into any Kdenlive project
3. Insert it into the project timeline
4. Move the cursor between the beginning and the end of the WAV file
5. Play the preview
OBSERVED RESULT
Audio is not played (at least, the relevant audio track).
EXPECTED RESULT
WAV file should be heard.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Neon, up to date, Plasma 5.18.1, KDE Apps 19.12.2
(available in About System)
KDE Plasma Version: 5.18.1

ADDITIONAL INFORMATION
Audio editing / previewing / cutting work perfectly when using WAV files from
other sources (though I only tried a couple of them -- incl. with the same
bitrate / frequency) and with MP3 files. Audio is played when the cursor is set
before the inserted audio sample.
