I just installed Music Maker and cannot get any sound. I could not find any help on your help system. All my other programs still have sound. What's up?
Welcome to the Magix user to user forums. So, this is not "our" help system!
Please help us to help you by reading this post and giving us ALL the information requested there. At the moment we don't even know exactly which version and variant of MM you have.
Then take a screenshot of the Program settings>Audio/MIDI tab and post it here. That should enable us to suggest how you might resolved the problem you are experiencing.
