tutu1290013 As Spinebot answered, there are several audio-related bug fixes between 4.2.20 and 4.2.40, so it is possible that there is some change in behavior. However, WAV and MP3 are still supported, so if they do not play at all, it is possible that the audio device is not working properly. If you do not see any audio logs, please open the spine.log file. Also make sure that the audio device selected in the audio view is the correct one.
