I have the same issue, no problem with speaker or with some kind of headset. There was 2 updates I installed yesterday and got it working one time. Several reboots, trued different network and cellular (3/4G) but same problem. This definitely feels lite software issue and would love to see a fix for this is really annoying.
I have June Patch and no working earpiece :/
Are you sure the culprit is the security patch?
I will keep an eye on this here and check if we see this issue in the tickets as well.
Could you tell me where are you all located?
