When I play the song in LMMS, it works, but there is no sound in the export wav file although the length of the wav file is correct. This is happening with all projects, including the demo projects included with LMMS.
OS: Windows 10
LMMS: v1.2.2
Audio Interface selected: SDL
SOLVED: VLC player was muted!
