Following-up: I got a lot of examples of it happening last weekend, but before sending them over, I wanted to experiment with the sound settings, and what I found was interesting.
The issue seems far more prevalent when sound is set to Headphones or 3D Headphones, but much less noticeable when set to Speakers.
So I've been playing with Speakers as my setting and trying to get more examples. I've recorded a few instances of issues, but nothing I'm too confident about without taking to carefully review my clips (which I'll try to do tomorrow, if I can). Here's what I've noticed:
- Estimating the location & distance of sound's source has become easier
- I can hear clear footsteps from farther away
- Footsteps only seem to be missing when there's a lot of other sound, too
That last point implies to me that either:
- Not a bug: Footsteps are playing, but are quieter than other things. (This implies it's a design choice, which wouldn't be my preference, but that's not my decision)
- Is a bug or Accidental: Footsteps have a lower priority than other sounds and are getting dropped when too many others are happening at once. (There are issues with memory usage right now and this issue has become more noticeable recently, so this would make sense).
Anyway, I'm going to try to send you some examples of gameplay with each of those settings.
Side note, I'm seeing clearly why squashing bugs can be so difficult... those devs deserve a case of beer or something.
