The sound team is continuing to investigate the issue that have been reported. The problem, honestly, is that some experience it, some don't. Different setups, etc. can impact the issue.
For example, I have never had an issue with footsteps, sounds, etc.
(I was once called a hacker because I heard the dude walking around the south side of the building and when he entered the open doorway, I 180'd and shot him in the face. I could hear him really well - I have an onboard sound device and use A40s. Same with console, though.) So, NOT saying it's not affecting some folks, and with a game like Battlefield V, sound IS key, but it's a difficult issue to lock down due to the variables and non-consistency of the issue.
TL;DR - I don't have any update to share at this time other than they are continuing to look into it.
