Updated yesterday to the new patch, the sound bug initiates within a single alert every time. Had to keep playing with 10-20 minutes left with sound drop out and need log in to refresh it Today same thing, playing one alert, 40 minutes left to the alert, sound bug. At least before it would a few hours at least
45 minutes into Amerish, no alert, can hear the weapons fading in and out when fired which means it will drop out in a minute or two and I rebooted prior to map change
I also have the sound bug, only selectively haring some sounds. This happens now every playthrough and I ended not rebooting each time as the gameplay would be a perpetual reboot. I am trying to play like this but for less crowded battles it's a really game-breaking feature as you can't hear where you are flanked or ambushed by an inflil.
