| i start to use the Motion sketch tool i cant hear the audio. |
this is a known bug from CC2015 : known issues in After Effects CC 2015 | Creative Cloud blog by Adobe (all the way down)
this is from the article:
When you use motion sketch to animate a layer’s position, or animate a puppet pin by holding the Command (Mac OS) or CTRL (Windows), audio does not play.
We are investigating these problems for a future update.
To work around these problems, you can open your project in After Effects CC 2014 (13.2), use the motion sketch or animate a puppet pin in that version, then save the project file and open it again in After Effects CC 2015.
