Footsteps are still silent sometimes

I have a pretty good headset that works just fine most of the time.  Nevertheless, I've experienced this audio bug in games, also seen/heard my friends while I was spectating them, and I've seen it happen to multiple Twitch streamers many times in the past couple months.

I have identified what I believe to be the main issue with the audio that remains somewhat inconclusive amongst different sets of gamers and their equipment...

1. Whenever there is NO nearby combat audio happening, players are able to hear periphery sounds (even ones behind them) just fine.  I've never seen anyone have this problem when not in a fight.
2. However whenever there IS nearby combat audio (gunfire, explosions, rez, abilities, etc.) happening near a player, the game is not registering those peripheral sounds whatsoever.  Sounds that are more than 90º left or right of a player, OR maybe outside their actual view, will not hear ANY AUDIO for actions happening adjacently or behind them.  This includes not being able to hear running, sliding, climbing, ziplining, settting up a zipline, and more.   This is entirely unacceptable because it becomes an audio blindspot from which 3rd partying is dramatically easier.

Unfortunately I have not been able to test these scenarios with 2 other friends in Shooting Range, because they kinda suck and they don't want to put in the minimum level of effort to fix the game.

Go figure HAHA

If someone else can verify this in the shooting range, that would be awesome!  Otherwise I have never observed (so to speak) this not happening in the way that I just described.  It'd be cool if other people can weigh in on this, so we can get closer to getting this audio issue resolved.
