OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/Xfce Qt6 ADDITIONAL INFORMATION Shotcut has the same problem and this will be corrected in the next version. https://forum.shotcut.org/t/v24-06-26-audio-quality-loss-for-wav-files/45183/2
STEPS TO REPRODUCE sorry, here in English: Inserting a 1-channel wav audio into the timeline Playback only in the left channel in a stereo project. All other mono or 1-channel audio files (ac3, flac, m4a, mp2, mp3 and ogg) behave normally, i.e. they are played back as files in Kdenlive in both channels.
The problem only appeared with the Manjaro update a few weeks ago. The latest version of Kdenlive does not have the problems when I revert the Linux updates (with timeshift). However, the AppImage 24.05.2 has no problems with all current updates, but the Flatpak does. The problem seems to be caused by mbedtls2. When I do the upcoming updates, ffmpeg, ffmpeg4.4, libplacebo, mlt, mpv, x265 mbedtls2 is also installed, then mono is only played on the left. The problem is also with older Kdenlive versions and not only with the latest one.
For your information: All AppImages no problems. Flatpak: the current versions cause this problem, the old versions up to 24.02.2 no problem with the mono wave files.
