I've noticed this after 1.13. The audio just seems to go through both channels with no filtering. I cannot tell where any gunshots are coming from now. It's the same with animals too and maybe other sounds. However, zombies sounds and player sounds work fine and I can hear them all around me.

This occurs both when using stereo uncompressed and Dolby Atmos for headphones on the console. Astro A50 is my headset.

Edit: It could just be distant sounds that don't have directional audio as chickens seem to be heard correctly when near them.
