Ever wanted to have Co-driver calls play through headphones while the other sounds play through speakers? Now you are able to without hacking around a convoluted speaker setup!
Co-Driver Splitter is a plugin for recent DiRT, GRID and F1 games splitting audio between multiple devices. Now Co-driver, Spotter and Commentator calls will be played through a Communications device, while everything else plays over speakers!
This is a modification I wanted to do for a long time. I wanted to have calls playing through headphones, with everything else left as is. Some people claimed it’s just impossible due to the way audio is handled on PC – so I decided to give it a shot myself, and it turned out to be absolutely doable!
Without further ado, you can grab Co-Driver Splitter from here. Make sure you read the note to know if the game you want to use Co-Driver Splitter with needs 32-bit or 64-bit libraries!
Setting up audio
You don’t need to do much to make sure Co-Driver Splitter picks correct audio devices. All you need to do is to ensure that in Sound, your Default Communications Device is set to headphones, while Default Device – speakers or other device you want to play environment sounds through.
How does it work?
Co-Driver Splitter fools the games into thinking a 5.1 surround setup is used. However, Co-Driver Splitter downmixes the output back to stereo for all channels except the center channel. Instead, center channel is routed to headphones! This creates a nearly perfect separation of communications and environment sounds.
Co-Driver Splitter is designed to be able to work as a wrapper around XAudio 2.7, XAudio 2.8 and XAudio 2.9. For XAudio 2.7, you may need to apply a few registry tweaks which I will detail soon.
