No animation in Curves on using Bake sound to fcurves In Blender2.9 , on adding location drivers to the origin of a Curve, there is no animation eventhough the location values are generated by baking sound to fcurves.
Also using a Hook driver to drive the curves,creates no animation.Even trying with a Cube ,gives no result.
Also, there is an  Error - &quot;Invalid python expression &quot; . Since the location values are derived from sound , there is no option to link the driver &quot;var&quot; to this value.Tried using &quot;self&quot;,but no result.
How to resolve this?
In the 3D window go to the menu Object - Animation - Bake action, so to bake the sound created animation into an editable curve.
