I was playing near the end of the game to retrieve the IFF or whatever it's called. The abomination zombies begin to attack me. They make a long grunting death noise when you kill them. However, sometimes when I kill them the sound is magnified 3 times my actual volume level and disrupts the game sound and all I can hear is the loud grunting that lasts for a good 15 seconds. It's so loud and disturbing that I had to turn the game off. It reoccured many times. This happen to anyone else?
I thought my monitor was possessed.
