Greetings,
I've been using Videopad Editor for years now and sometimes the audio of the video I Imported are delayed when played using the clip preview and still delayed after I exported the video, I edit long videos 30 minutes or more with 1080p resolution 30-60FPS. This issue just pop-up at random and sometimes lasted weeks, but sometimes it just fixes itself. I tried clearing the cache; uninstalling and reinstalling Videopad; all Reupdating my drivers again and again.

Intel i5 6600
