Mirillis forum

So I have used action before but never for CSGO and when I used it for CSGO it did not record any in game audio? I have a rig as well AMD Athlon X4 860K Quad Core Processor, 16gbs of ram, Nvidia GTX 760, on windows 8.1. I never had any other issues with Action before this happened, I saw on another forum that someone had issues with their audio drivers so I uninstalled mine and reinstalled them and still no luck which is why I have came here to try and fix my issues so I can start recording CS. A few notes, action picks my mic up fine and perfectly, but as far as in game audio sound I am not sure and its very annoying.

Have you check some other games?
Maybe Action! settings are not set up correctly.
Please go to Audio settings tab and make sure your audio device is selected from the list.
