No Sound even though all API calls are a success

FMOD Studio
1

Hello, I’m new to Fmod and I’m trying to get it working in my C# project (based on Raylib). I have a SoundManager singleton that loads my banks (no problem), updates the system every frame (no problem) and gets the event and starts it (again, no problems). But I don’t hear anything whatsoever, no artifacts, no nothing. Any help would be greatly appreciated.

Hi,

What version of FMOD are you using (i.e. 2.xx.yy)? Could I get you to make sure you’re using the logging version of the FMOD libs (with the “L” suffix), then use Debug_Initialize to set the flags argument to FMOD_DEBUG_LEVEL_LOG, and post a runtime log where the issue occurs?

Hello. I am using 2.02.26. However, I wasn’t able to get the L libraries to work. Is it just those that I need, or do I need the regular fmod DLLs in my build folder as well?

EDIT: scratch that, I changed the DLL strings in the wrapper scripts. But I see no log output in the console and no log files created

EDIT 2: scratch that again. I got the file output working, and there is in fact an error:

[LOG] Manager::readBank                        : fileversion = 142, compatVersion = 140 (oldest = 44, newest = 142)

I’m certain the path is correct, otherwise there would have been an exception no?

Thanks for the log!

There’s a couple of potential causes based on the log info. Assuming that path is correct and the bank is in the correct place, it’s possible that:

  • The banks are encrypted, and an encryption key hasn’t been provided
  • The bank metadata and assets have been separated, and the non-streaming/streaming asset banks (*.assets.bank/*.streams.bank) haven’t been loaded alongside the metadata bank (*.bank).
  • The banks are corrupted in some way, and may require a rebuild in FMOD Studio

I’d recommend verifying that none of the above are occurring.
