Annoying alert sound when pressing spàcebar or..

[default7s8ubk4hzh75]

Sometimes when Im drawing with brush and press spacebar or other keys on the keyboard an alert sound is made.

So frustrating...why? when I got out of the program...alt tab or x, the sound stops , but how can I turn it off¿?

is this a bug? how how can I turn this sound alerts?

i've never heard a sound alert in any flash/animate version though i've encountered many warning/error dialogs.

if animate were doing that, if would resolve by resetting your preferences,  https://helpx.adobe.com/animate/using/set-preferences.html

the easiest solution would be to ignore it or mute your speakers while working in animate with the brush tool.

This does not solve the problem whatsoever.
I am still trying to find the solution for this. 
This is unbelieavable! What a frustrating experience!
