the sound no longer works on my projects and the projects of others, while I but the sound at maximum.
This indicates that the sound lasts 0 seconds and marks just one line.


What should I do to resolve this?

Are you on mobile? Or on a computer? If you could provide more details that would be great.

See if it is your device's fault
If possible, use another device to view the same projects. Is the sound working? If so it is your computer. Check if the tab is muted.

My computer and the tab is not mute, my brother can hear but not me.
Some project the sound works very well.


it's a bit annoying


but ,maybe it has something to do with my storage space being full
