Fmod Freezes when i open the Mixer window

FMOD Studio
1

Hello,
I’m experiencing a blocking issue here. Fmod is freezing after opening the mixer window. It happens only in one project. Yesterday it was unfreezing after several minutes, but today it’s completely stuck.
Thank you.

Details:

  • Version: 2.03.06 but I already tried to open it with 2.03.07 and the issue persists
  • OS: Windows 11 Pro
  • Machine: I9 13900K, 64Ram DDR5, PowerColor Red Devil AMD Radeon RX 6700 XT
  • It behaves the same with Unity open or closed
  • The CrashReports folder is completely empty
  • Already tried to remove/rename the Studio.02.03.00.config
  • Already tried to empty the UnsavedProjects folder
  • Already tried to uncheck Remember window position option
  • The Event Editor window and the live updates seems to work properly. I can build.
  • Two weird scrolling bars appairs in the Mixer’s overview window while crashing (see attached screenshot)

  • Already tried to save the project as and open the duplicated one.
  • Already tried to switch audio interface and from Wasapi to Audio.
  • In the logs, two errors appear: 2025-06-10 09:34:27 “FMOD_ERROR (27): Cannot call this command after System::init.” ----------------- ! 2025-06-10 09:34:27 “FMOD_ERROR C:\buildagent1\work\c1c3f17eb167c494\studio\src\SoundSystem.cpp(131): system->setSoftwareFormat(deviceInfo.sampleRate, speakerMode, 0)”

Here’s the latest log:

Hi,

Thank you for sharing the detailed information and log file.

Unfortunately, I was not able to reproduce the freeze on my end, would it be possible to upload the project or a minimal reproduction to your FMOD profiler so I can take a closer look?

Also, FMOD Studio 2.03.09 is now available on our website’s download page. This version includes fixes for some Qt-related UI hangs. Could you please try updating to 2.03.09 and let us know if the issue persists?
