Therefore Dewesoft offers special control buttons: Start/Stop, Sound output selection, Replay mode for selection different ways of replay, Replay direction and Replay speed in different Display Screens, which you can find at the top right part of the window:

If we click on it, the channel list will appear to select analog input channels for output to sound card. Choose the only channel we have stored and the loudspeaker will not have a red cross anymore. Now press again a Play button and whatever we have recorded will be heard from the loudspeakers.
