I believe they are looking at the audio mix on an ongoing basis.
"AUDIO FIXES AND IMPROVEMENTS
One of our biggest issues to tackle was improving the audio performance to address issues reported of sounds dropping out, sounds missing for extended time, or distortion for a period of time. We have made improvements both in our code and with our content that will hopefully fix these issues for many players, and for others, at least lower the amount and length of time they encounter audio issues.
We have also addressed some of the other mix issues with the game, including increasing the volume of close proximity enemy footsteps and lowering the overall volume of the game from the character select screen to the end of the drop sequence. We will continue to monitor mix issues and address them as necessary. Below are the notes of improvements we’ve included in today’s patch and we’re continuing to work on future improvements.
Improved audio engine to be around 30% more CPU efficient, lessening the chance of distortion or dropouts.
Lowered impact on data loading through code and content changes to improve potential dropout issues."
