I ran into this audio bug when I first started started playing. It made the game unbearable to play so I sat on the game until the latest patch where it was seemingly fixed. Unfortunately, the bug came back today and I still have yet to find a solution. I've looked through the games audio settings multiple times, I've looked through my PC's audio settings and my audio interfaces settings multiple times, but I've yet to find an issue occurring on my end. No other game or application has this issue, it is only Deadlock.
