Thanks Dan, I have switched to this and will test.
Something that started happening after 4.18 in the Linux build of my game was that the reverb sounded more pronounced than on Windows. Enabling the new audio engine on Windows now yields the same result (I missed that the new engine was made default in the Linux version of 4.18). It’s all making sense.
Thinking about other developers, it would have helped me immensely if there was some documentation for UE4 stating that there are problems with AMD FX CPUs and XAudio, and that the new audio engine alleviates these. I get that the goal is to transparently make it the default in a later engine version, there’s just very little information around this to help figure out what is going on.
Thanks!
