Trust me that has been done multiple times already.. No luck. If you look at the link I postet, other people are having the same issue and they installed The game after the update. Bug report as been filed to cyanogenmod but it does seem to be a specific problem with the walking dead and android 4.4.4 as everybody who is having this issue seem to be running Android 4.4.4. Every other game seems to be working fine only the walking game has this sound buzz bug.
