My application(game in SDL) uses **FMod library.** I’ve a problem with the **3D Listener position** (it **doesn’t update for some reason** ). I **change the attributes every single frame** and call System::update() also, but it doesn’t work. If i put an audio in a position it works(I hear it from the left or from the right depends on the start position of the audio). The problem is when i move the player(who changes the position attributes of the Listener) and it does nothing.
Update of the player be like:
> AudioEngine::getInstance()-\>getSystem()-\>set3DListenerAttributes(\_listenerNumber, &\_attributes-\>position, &\_attributes-\>velocity, &\_attributes-\>forward, &\_attributes-\>up);
Update of the system:
> \_system-\>update(); //\_system → System instance
Also i set up the 3D Setting in the System and Channel.

Have you tried checking the `FMOD_RESULT` that all FMOD functions return? If there is a problem then this will give you an idea of what it is.
Are you getting anything in the output log? (While using the FMOD logging library).
