"Failed to initialize any audio devices" exceptions prevents to connect game servers


We’ve been receiving reports from players which can’t play / connect our game servers after a " FMOD failed to initialize any audio devices, running on emulated software output with no sound. Please check your audio drivers and/or hardware for malfunction. "

The game is launched normally “running on emulated software output with no sound” when you disable all audio devices on Windows, but there are other related FMOD exceptions which cause that players can’t connect the server.

" Forced to initialize FMOD to to the device driver’s system output rate 48000, this may impact performance and/or give inconsistent experiences compared to selected sample rate 48000

(Filename: C:\buildslave\unity\build\Modules/Audio/Public/AudioManager.cpp Line: 1469)

FMOD failed to initialize the output device.: "Error initializing output device. " (60) "


" FMOD failed to initialize. This may be because your sound card is configured to give applications exclusive access, thus preventing Unity from using this device. You can change this in Control Panel > Audio Devices and Sound Themes > Playback Device > Properties > Options … : "Soundcard does not support the minimum features needed for this soundsystem (16bit stereo output). " (59) "

FMOD should keep “running on emulated software output” and let the game run normally with no sound, am I right?

Many thanks!

Looking at the location of that error C:\buildslave\unity\build\Modules/Audio/Public/AudioManager.cpp and the wording of the error messages it sounds like they are coming from the built-in FMOD audio system. For reference Unity’s internal audio system is built on FMOD4, have you tried disabling built-in audio?
