Created attachment 161884 [details] OBS Settings if its helping SUMMARY I regularly edit videos about every 2 - 3 days and use .mkv videos from OBS with 4 different audio tracks. For about 2 weeks Kdenlive has stopped reading them properly, 4 audio tracks are being imported, but they are all identical. Kdenlive only imports the first audio track 4 times. I thought it might be because of the few videos, but now it's the same with all videos. The videos themselves actually contain different audio tracks, as I can also access them in VLC. I'm currently working around this problem by importing the tracks into Audacity and then exporting them as an audio file and then importing them into Kdenlive. STEPS TO REPRODUCE 1. Get .mkv video from OBS or other source with multiple audio tracks 2. Import into Kdenlive 3. Wait until Audio available in Kdenlive OBSERVED RESULT 1 Videotrack Multiple Identical Audiotracks EXPECTED RESULT 1 Videotrack Multiple different Audiotracks SOFTWARE/OS VERSIONS Kdenlive 23.08.1 MLT Version 7.18.0 ffmpeg Version: 2:6.0-10 (Manjaro Repository) or Version: n6.0 (ffmpeg -version) Operating System: Manjaro Linux Plasma Edition KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 Kernel Version: 6.1.53-1-MANJARO (64-bit) Graphics Platform: X11 HARDWARE INFORMATION Processors: 16 × AMD Ryzen 7 3800X 8-Core Processor Memory: 31,3 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3070 Ti/PCIe/SSE2 Manufacturer: Micro-Star International Co., Ltd.

Thanks for your report. This was caused by a change in the MLT video framework. I am working on a fix for 23.08.2
