Conduit Sound Loop

[bcda12]

Hi, im able to play the Conduit at decent speeds, but i sometimes the game will hang with a sound loop whenever a character speaks, e.g. when you find the big portal int he first level and the dude on the radio goes 'This is what we've been looking for' - that line is constantly repeated and nothing happens, the game is hung

does anyone know how to fix this?

thanks
