Dominus' lightning beam screws up my sound since the latest patch

Hi everyone,

anyone else having problems with the audio, after Dominus' casts this continuous lightning beam? It's all fine, until that happens and then extremely loud (like at 100% volume, even if I only have about 20% enabled) sound effects start to occur randomly, like water flowing when I'm in Sarn encampment, monsters growling, a banner flapping in the wind etc.

Restarting the game helps, but it comes back right after the next Dominus run. Have been running Dominus just fine the last few days.
