Hello,
I’m experiencing an issue with FMOD 2.01.11.
When running my project in the Unity Editor with Live Update enabled, a crackling noise started appearing - similar to the sound of a faulty physical audio jack. I tried switching between multiple output devices, but the issue persisted.
I used the FMOD Profiler to diagnose the problem and found that when I record a session and then play it back in Waveform mode, the issue becomes significantly worse - the noise becomes constant and continuous.
Notably, CPU usage never exceeds 15% at peak, and the number of voices and instances is well within normal limits.
I initially thought the problem was in my Unity project, then in my FMOD project, but I discovered that even in a completely empty FMOD project - with just a single event and a single parameter - the issue reproduces in the Profiler when playing back in Waveform mode. I’ve included a video link below where you can hear the noise in this empty test project:
As a comparison, I created an identical empty project in FMOD 2.03.13, and the issue did not occur there. However, upgrading our production project to a newer version would require a significant amount of time and effort, so I’m hoping to find a solution that works with FMOD 2.01.11.
I should also mention that I have completely uninstalled all versions of FMOD from my PC, removed all leftover folders (including %AppData% and %LocalAppData%), and performed a clean reinstall - unfortunately, this did not help.
Our project has been using FMOD 2.01.11 with Unity 6 for a long time, and this issue only started appearing recently. Previously, everything worked fine.
Thank you in advance for your help.
Best regards,
Vsevolod A.
