rafa_es : I changed a bit your game so that the only difference between the java sound test and your game is that your sound node is added to a render branch (pass).
Marvin, are render passes and regular branchgroup handled differently about sound nodes ?
The sound data is only loaded, when it is first “rendered”. And when it’s loaded there’s a message. And, we don’t have this message… so this node never gets rendered… and when it’s not in a special “pass” it works perfectly… soo what’s going on ?
