Why does "stat audio" show that 0MB is used? (while 30+mb soundwave is playing)

Hi guys!

Why do “stat audio” and “stat memory” commands always show that 0mb is used for audio?
I have 30+mb song currently playing in game, it can’t be zero. Is it a bug?
How do I monitor my RAM usage for audio?

Thanks!

If you turned on or off audio stream caching then you need to restart the editor and run the game in stand-alone I believe.
