p：流和自动播放的媒体问题

我有一个带有文件列表的数据表，其中一些是声音文件 . 如果我使用流Firebug说网络错误404.我通过编写文件使其工作（但param autoplay = false不起作用），但它是一个丑陋的解决方法，我可能错过了使流工作的东西 .

萤火虫说：

“NetworkError：404 not found - http://localhost:8080/Projet/javax.faces.resource/dynamiccontent.properties.xhtml?ln=primefaces&v=5.3&pfdrid=1G8w72KY96Ob6Ye0QRtzBg%3D%3D&pfdrt=sc&pfdrid_c=true”
