sound source

Hello

first I want you to excuse me for my bad English (i'm french)

this is my problem

I have in my 3D scene a Boeing 747 (mesh), I want to attach a sound to this plane, the problem is the source sound start from the camera and not from the Boeing

this is my code source

You have to attach an OgreAL::Listener to the same node your camera is attached to, something like this:
mCameraNode->attachObject(mCamera);
mCameraNode->attachObject(mSoundManager->getListener());

I try many things without success

like this
SceneNode* camNode = mSceneMgr->getRootSceneNode()->createChildSceneNode();
camNode->attachObject(mCamera);
camNode->attachObject(soundManager->getListener());


i try also this


SceneNode *node;
node = mSceneMgr->getRootSceneNode()->createChildSceneNode("CameraNode");
node->setPosition(0, 100, 100);
node = node->createChildSceneNode("PitchNode");
node->attachObject(mCamera);
node->attachObject(mSoundManager->getListener());
node->pitch(Ogre::Degree(-30));

help me please

I hope your sound is mono.......

Yes for the test i use roar.wav so i think is a mono sound

Well then there is very little else to cause the problem, either your sound/listener ARE close together or your sounds properties are incorrectly set.
