Cannot hear the audio at the timeline!

Ok, i'm at Adobe Animate, suddendly all the audios i try to play at the timeline aren't playing! It sounds only if i play the animation since the first frame, if i try in mid the anim it doesn't play neither, if i try scrubbing through the timeline, still not playing. I tried whit a file from before it happens, it works perfectly, but if i import any other audio into the old project, or if i grab the audio from the old project to a new one stills not playing, like if anything i move ruins it, bringing it to the actual chaos, anyone else whit this issue?
