Hey everyone, im using a DFPlayer mini on a game that im making and I'm pulling my hair out with this one, sometimes it works and sometimes it doesn't which makes this more irritating. I'm using it to play sound effects when a button is pressed and during an intro animatiion but most of the time it'll play the track once, then it won't play the track again, then it'll play it the next time. I'm not using alibrary now as I get the same results regardless but this is what I'm sending it:
