Inside the MC200 there is a ribbon cable that runs from the motherboard to the sound card. Sometimes one of the connectors is a little loose. It is a common cable in building PCs so if there is a good possibility you can pick one up locally. This is assuming it is not under warranty. Pay close attention or take pictures before disconnecting the cable as there are a number of adjacent connectors that the cable can fit.
