When we use MXF video in Premiere, we encounter an audio issue. The audio waveform is visible, but there is no sound. Closing and reopening the program fixes it, but then it disappears again. There is no such issue in Premiere version 24.6.8, so I have to use that one. The same problem persists in the beta. The info for the video with missing audio is as follows:
