It's funny because "audio bugs" are one of the most frequent complaints in the Apex community. But that's probably just because the players have gotten so used to depending on spatial audio when it works properly, that they get especially frustrated when it doesn't.
I've always found the complaints about audio weird. It almost seems like something that plagues consoles or low end hardware? I only say this because I'm a day 1 player of Apex and can maybe think of a half dozen that audio has failed me, but for known things like the super quiet Octane pad landings having no audio or prior to Ashe's ultimate being made louder. But if you go to the Apex subreddit, especially daily threads there are dozens of users complaining about it as though it is a pervasive issue that everyone should care about. Is it random, but I've been lucky? Is it poor hardware? Is it only on consoles?
Doubly interesting knowing that both their engines are descendants of Source.
