Audio muted when doing stutter loops

[Mertekz]

Describe the bug
Audio is muted when doing stutter loops (copy/pasting the same 1 frame clip multiple times), but video is fine.
Splitting the clip to 2 frames seems to fix the issue, but its still annoying.

To Reproduce
Steps to reproduce the behavior:

1. Open Shotcut
2. Open a file
3. Drag it into the timeline
4. Split the clip at 1 frame
5. Copy paste it multiple times
6. Play the timeline/Render the video

Expected behavior
Expected the audio to be affected,both in playback and in render

Desktop (please complete the following information):

• OS: Q4OS
• OS Version: 6.1
• MLT/melt version: 7.32

Additional context
Rendered video/screenshot for reference:

Forgot to tell this is the same issue both in flowblade and kdenlive also

I confirm this observation. I also tried a test with a .wav file. No sound is reproduced when repeating one frame, but repeating two frames does produce a sound. There must be a two frame minimum somewhere in the code.

New release, will look into this sooner.
