Hello I am now developing a PS4 game and try to output sounds from the speaker in PS4 controller. I have found an example in low level API, but since I would like to use FMOD Studio to create events for the sounds, I would like to ask if I can play the sounds by using the events I have defined in FMOD Studio instead of directly loading the audio file (just like the method used in the low level API example). Thank you. Regards Sunny Cheng ---

If you use the functions [Bus::getChannelGroup](http://www.fmod.org/documentation/#content/generated/FMOD_Studio_Bus_GetChannelGroup.html) or [EventInstance::getChannelGroup](http://www.fmod.org/documentation/#content/generated/FMOD_Studio_EventInstance_GetChannelGroup.html) you can play events through the controller speaker using the code from the low level example. ---

I have successfully get the channel group using EventInstance::getChannelGroup, but in the code from the low level example, a FMOD::Sound pointer is also needed when calling FMOD::System::playSound() to output sound to the speaker in PS4 controller. In the sample code, it creates the FMOD::Sound object by directly loading the audio file. Are there any methods which I can create the FMOD::Sound object by using the event name defined in FMOD Studio? Also, I have tried to add a self-created controller channel group, which is similar to the ‘controllerPort’ object in the low level sample code, to the retrieved channel group as a child, but it does not work. Is this a proper way to output sound to the speaker in PS4 controller? If possible, may I have some sample code for this issue other than the low level example? Thank you. ---

You’re overthinking things. Just take the channel group from the event or bus and call attachChannelGroupToPort() with it. That is all. ---

Thanks Nicholas. It works when I attach the channel group retrieved from the event instance to controller port through low level system.
