After I unlocked the 'horror' speechbank on the grave digging mission I cannot test any speechbanks, they are silent. And I turned down the music in the music options as the 'shake your coconuts' song was really
starting to get on my nerves, but between missions it automatically turns back up, or sometimes turns down.
Even with quite a few glitches this game rocks!
I've mastered the controls and happily getting on with the campaign mode.
Gotta love the new worm clips between missions!
