I can confirm this is still happening.
I am a MAC (OSX) User and I experience the same problem in combat sites, especially mission sites. 
Yep, it’s annoying.
I lile playing games with sound on, even EVE. But I recently tried again and turned it back off.
Please fix this audio bug.
Same herre, issue not resolved yet. Please fix this, as I really miss the immersion and I realize that I am currently not playing much and avoid clearing any sleeper-sites.
I have this same bug. Really annoying.
