Comment 1 Matthew Pocock 2023-10-06 21:38:14 UTC 
This is broken for me also. I record game audio to one channel and voice to another. In 22.12.3, the two audio channels were correctly handled when I dragged the video into the main timeline. In the clip view, only the lowest-numbered audio track could be heard, but both histograms were visible. In 23.08.1, it shows two audio channels, but they are clones of the first audio channel (game sounds). The second (voice) channel appears to have been lost and replaced.

The audio is handled correctly in kdenlive-23.08.0-x86_64.AppImage but not in kdenlive-23.08.1-x86_64.AppImage, so I guess that gives you a bisection point -- however, there's an issue with some of my videos being truncated that is fixed in .1 but still broken in .0 so I guess I'm stuck for now.
Comment 3 Jean-Baptiste Mardelle 2023-10-07 06:23:57 UTC 
This was caused by a change in the MLT video framework, and has been fixed in the soon to be released 23.08.2.
