The Firestation needs to install 3 types of drivers: MIDI (first), WDM, and ASIO. If 3 installations do not automatically come up, audio will not work, and you need to force it to install the other drivers. Luckily, it is simple to do this. Go to your MLAN control panel, check WDM, hit SET, uncheck WDM (forces it back in ASIO mode), hit SET, and it should find new hardware twice. Simply point it to the driver CDrom for the drivers, and this should solve the problem.
