@Puga Hey. Sorry to hear that 
I downloaded the version above but still having the issue
Hmm that’s the thing, I downloaded the first file and I could play it on loop consistently on the same download version I mentioned 
Perhaps as scribblemaniac suggested above have you been using the “jump to start” button during playback to go to the first frame? Indeed if you do this the sound will not come out the second time, but this is the only case (so far) that we know about and it’s on the bugfix list already 
I downloaded the new ghosting wip file and I left it play around 10 times with the loop button enabled but it worked properly like an audio player would, so I don’t really know what could be happening on your end to be honest 
also forgot to mention it previously but there are purposefully no frames, ive been wanting to create an animatic but for that I’d like my continous sound
Yeah by default you get only 1 frame container at the start. Imagine you get a paper sheet or film sound track for free to start with, then you have to add only what you need, no need to repeat the frames as this is done automatically by the program until the exposure (how long the frame is shown over time) hits the next (key)frame container.
Sounds are specially loaded into their own frame containers. So one sound = one container which adapts to the length of the actual wave form. When I open your files I see the single OST in a continuous frame laid out properly, are you not seeing this? or do you need something else to occur?
FYI You can have multiple sound frames in a single layer, or create multiple sound layers to overlap sounds, however currently there’s a limitation where Pencil2D can only export up to 64 sounds, or else there will be an error, but even with this limitation lifted we always recommend to add the sound work to a video editor, and use the sound layers for dialogue and specific sound cues in case you’re animation to music or particular sfx.
