We're aware of this issue and it should be fixed soon. In the meantime, it's just a visual bug. If the Soundblaster keeps getting stuck on your head and doesn't come down the elevator, it's because it's already in your inventory, or because you've already given it to Zolio and you don't need it anymore.

If your journal keeps telling you to give the Soundblaster to Zolio, but you've already done so, you just need to move forward and the journal will update at the next cinematic.

Take the rope behind Zolio's camp, go up and then turn left – you'll then be able to continue playing the game!
