Multiple matches I can not hear players (friend and otherwise) that are not in my line of sight
examples
Villa - Smoke sprinted up to me from behind, shot gunned two times, then killed me. Did not hear anything at all
Sub - Was in control room, Cav without silent step climbs the ladder. Kills my teammate with a her SMG who is directly behind me then me. Again did not hear anything. Teammate did not hear anything as well
Chalet - Holding angle in bedroom, 3 Armor enemy walks in (not crouched, not slow walking,) reloads in gets beside me shoots me.
My sound setting did not change that are the same as they were last season, over the last 7 years I have had less dropped or sound bugs combined then I have had in the past 2 days of this season.
