Get rid of this continuous growling by Zombies.

For crying out loud. Get rid of this unrelenting continuous growling by zombies, even in my hideout.

It is utterly irritating. At least give me an option to turn it OFF.
It is one of the reasons i keep quitting the game, along with the idiotic experience penalty upon death.

After an absence of over a year i'm just starting the new league which is very promising, but already the zombies are driving me crazy and i probably won't last more than a month or 2.
