Issue with editing sound in Animate
Hello,
I am fairly new to working with Animate and I am having difficulties working with editing sound. I have to create a HTML5 project, include sound and use the edit sound envelope. I have added my audio files to the library and on my timeline, however the effect and edit sound envelope options are grayed out and I can not use them. I just finished the practice lesson where both buttons worked previously, I do not know what to do now.
