I just compared playing my latest saved version of my game (not the sound test one) with playing a stand-alone older version that I exported months ago. The old one’s sound works fine but the new one’s sounds are messed up. However the sounds used and the events used to produce the sounds are unchanged. Could it be that the old version works because it was created with an older version of GDevelop and the new version doesn’t work because it was saved with a newer version of GDevelop?
