Today I had an odd issue with my Kraken 7.1 Chroma:

I could not hear the voices in a movie in VLC.

I could however hear the other sounds (like the voices were filtered out). I could also hear everything with the internal speakers or one of the monitors...

I've tried finding answers online but the only bits I could find were for Windows. So, without further ado, my solution is to install Boom 2 (as a trial). I've ended up buying it because it boosts up audio nicely.

If you have other solutions, please let me know :)

HTH,
