How do I control the volume for the Audio Input Plugin?

0 votes

Hi there! I'm using the Audio Input Plugin ( to play VOIP in our game and I can't seem to figure out how to control the volume it plays back.

We have two audio events associated with the VOIP, to start and stop the stream. We also have an RTPC parameter setup that should control the volume of the VOIP, but doesn't seem to have any effect.

I have also tried using the AkAudioInputPluginGetGainCallbackFunc to set the gain manually. I have confirmed that that callback is being invoked, and returning expected values in the range of 0.0f - 1.0f (per the documentation), but still there is no effect.

I'm wondering if I've missed something, or if anyone else has any ideas?
