p:media problems with stream and autoplay - jsf

Question

I got a datatable with a list of files, some of them are sound files. If I use a stream Firebug say a Network error 404. I made it work by writing the files (but param autoplay=false don't work), but its an ugly workaround, I'm probably missing something to make stream work.
Firebug says :
"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"
<p:dataTable var="doc" value="#{besoin.document}" id="besoinTableDocument"
draggableColumns="true" resizableColumns="true"
scrollable="true" scrollHeight="150"
selectionMode="single" rowKey="#{doc.id}">
<f:facet name="header">
<p:commandButton value="Upload" icon="ui-icon-extlink" onclick="PF('dlgupload').show();">
<f:attribute name="filId" value="0" />
</p:commandButton>
