I cant work this out!

This is to adjust volume of incoming audio samples by just multiplying by a constant value (SW). I wanted to be able to control the volume value with the switches on the DE2 but i get no sound at all...

You could try registering your signals and then use signal tap to check your circuits logic. If it works with registers then it is probably a timing issue. If it still isn't working you should be able to see where your errors are, like switches not working correctly.
