Default [Q] Remove audio folder GTA San Andreas Android?

Hello,

Is it possible to remove the audio folder from the main.6.com.rockstargames.gtasa.obb file?
When I remove it using winrar, the game gives an error on startup.
I want to do this, because then the file will be 1.10GB less and will give a speedup.
I'm using an android 4 rom on a xperia play.
