I downloaded LMMS a couple days ago. I was able to use it and was getting familiar with the program and everything was fine. I had a project started, but now the sound settings keep reverting back to dummy. I get the message that some settings will not be saved until I restart, but it keeps going back to dummy. I had the settings on Windows DirectSound and Primary Sound Capture Driver when everything was working fine. When I try to change it back, but it keeps going back to Dummy. I have restarted the program several times and even reinstalled the program. I can see the master sound moving normal when I press the keys for a beat, but there is no sound. What can I do? I have Windows 10 64bit
