ae preview starting from last rendered frame and muted

For some reason, in my composition, whenever I start preview it jumps to the last rendered frame. And there's no audio, this has been happening for a week now and i don't know what to do. I've uninstalled and reinstalled ae, i checked all the files, reinstalled, and it just doesn't  work. My specs are gefore rtx 3060 and a ryzen 5700x with 2*8g of ram, if anybody knows that could be causing this
