Audio dropout specifically when playing Vindicta

[Edravel]

I'm experiencing a recurring issue where the audio breaks while playing Vindicta. Specifically, certain sound effects disappear—mostly gunfire, ability sounds, and teammate voice lines/weapon sounds. This usually triggers after an intense combat encounter. The issue is character-specific and persists until the game is restarted.
I should also mention that the issue arises when the character's rate of fire increases, typically after 10-15 minutes of gameplay. I have already tried reinstalling all drivers, but the problem persists.
