[PS4] Crackling sound

Eshenya

I bought the game just a few days ago and upon first launch, after having installed all updates, the sound would crackle throughout the entire intro and then would randomly do so in-game as well. There does not seem to be anything obvious connected to it that causes it as it even happens during the loading screen and regardless of which server I'm on.
ESO is the only game causing this so I can rule out any hardware problems.
Also, when I played the intro from the start menu, there were no sound glitches.

Does anyone else have the same issue and is there a fix?

Thanks in advance. =]
