Might want to turn down your volume
It seems to kick in right when the radio would normally play. All other sounds are normal, including the car radio while standing outside the car. I have no custom music or anything.
Setting the sample rate to 24 bit, 44100 Hz seems to have fixed a similar issue for other people, but it didn't change anything here.
I haven't had this problem in any other game. Anyone know what could be causing it?
