5.1 Main Sounds on 7.1 Sound Card via AudioBus?

Hello All,

I have a question about a project I am doing. I have a 7.1 PCIE sound card and the game needs 5.1 surround sound. Can I use the extra 2 channels for something else? I have heard of AudioBus but I don’t know how it works.

I thought I could send the main sound to the “Five Point One” AudioBus and use metasound with the “AudioBus Reader” to get the effect. But when I tried it, I only got the sound without the attenuation.

I read that if I use “Post-Effect Bus Sends”, the attenuation should work.

Can someone help me understand this? I am lost.

Here is my test map.
