Sound seems to be deactivated - can't change volume on timeline
I habe Premiere Elements 2021 and can't work with the sound. The sound effects don't 'stick' on the timeline - when trying, there's shown the 'not-possible-sign' (crossed out cirkle).
And moving the yellow line in the timeline doesn't has an effect. Neither with the whole line, nor with a part between keyframes - the volume doesn't change, even if the line is positioned very high or low.
Fading out an in don't work as well.
The clip-volume in the left above edge of the timeline is activated.
What can I do?
Thank you very much for your help!
Manuel
