Very low or missing sound and spell effects from other players in dungeons

[Moocowski-stitches]

I’m having a sound issue that seems to be only when I’m in a dungeons or party. The sound from other players and their spell effects are very very low, or sometimes missing, I can only hear my own sound effect, the sound from mobs is also really low. I have tried to disable distance filtering, but that didn’t help, also tried to disable speaker enhancement in Windows, that didn’t help either.

Anyone else have this experience or maybe know how to fix?

Seems to be quite few players with the same issue. I also have this issue, it only occurs in instanced content

Same problem here.

I also experience this, and a lot of other players as well.
Asked a couple of randoms in my dungeon group and they had the same issue.
