My wife and I are having the same radio. We are on T-mobile. I tinkered around with the phone and figured out it has to do with T-Mobiles HD+ voice calls. Unlike on the S7, you cannot turn this feature off. To test the difference go into settings-> connections-> mobile data-> and switch mobile data from LTE/3G/2G to 3G/2G and the staticy webcam voice will go away. I think it has something to do with the cellular radio in the phone. Not sure if users from other networks are experiencing the same issue.

Looks like this issues has been going on for the Tmobile variants since the s8 launched. Here is one other user with the same problem.
