Audio at speed < 1x doesn't play at corresponding position during shotcut play

What is your operating system?
Win10

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
22.06.23

Can you repeat the problem? If so, what are the steps?
if you place an audio sound effect (wav/mp3) inside the timeline, and change inside the property the speed to 0.4x or 0.8x and so on, the play button in preview screen heavily fails to reproduce the audio compared to timeline position.

Audio at 1.00000x instead is played correctly

At rendering everything is correct. The error is just inside the preview box

thanks

I cannot reproduce this. Maybe you are experiencing seeking issues on your audio clip as mentioned in the #FAQ. Not everything can seek properly because there are too many factors in media. There is some automatic testing for seeking and a conversion dialog when it fails, but that is not perfect and depends on the FFmpeg libraries we use. You should try Properties > Convert.

Are you running Linux or do you have access to a Linux machine?

no linux

Huh, so it’s not specific to Linux.
