@Djdj-17 Open the program settings under the File > Settings menu, then go to the Audio/MIDI tab. Here select the ASIO driver of your audio interface. If you don't have an audio interface you can use the Music Maker ASIO driver.. Then click on the Advanced button next to driver selection to open the ASIO driver settings. Here select the input and output device and set the ASIO buffer size to a reasonable value, for example 512 samples. Close the ASIO settings and close the program settings with OK. After that, you should have sound.​​​​​​
