ERR_INVALID_HANDLE on createStream() on Linux

gn.fur · January 31, 2021, 2:10pm

When I call createSound() on Linux, it returns ERR_INVALID_HANDLE. Windows and Android work fine. I am using 12.7 version of FMOD.

My code:

    public static Sound LoadStreamedSound(string path)
	{
	    var buffer = FileLoader.LoadFileAsBuffer(path);
		// Internal FMOD pointer points to this memory, so we don't want it to go anywhere.
		var handle = GCHandle.Alloc(buffer, GCHandleType.Pinned);

		var info = new FMOD.CREATESOUNDEXINFO();
		info.length = (uint)buffer.Length;
		info.cbsize = Marshal.SizeOf(info);

		var r = Native.createStream(
				buffer,
				FMOD.MODE.OPENMEMORY | FMOD.MODE.CREATESTREAM,
				ref info,
				out FMOD.Sound newSound
		);
		Console.WriteLine("LOAD RESULTS:" + r); // ERR_INVALID_HANDLE
		return new Sound(newSound, buffer, handle);
	}

Tested some more – and this behavior only happens if I initialize FMOD Studio (which wortks fine by itself). If I just initialize Core library, everything works as intended.

gn.fur · January 31, 2021, 2:25pm

This is how I initialize:

			FMOD.INITFLAGS coreInitFlags = FMOD.INITFLAGS.CHANNEL_LOWPASS | FMOD.INITFLAGS.CHANNEL_DISTANCEFILTER;
			FMOD.Studio.INITFLAGS studioInitFlags = FMOD.Studio.INITFLAGS.NORMAL;

			var r = FMOD.Studio.System.create(out StudioSystem.Native);
			Console.WriteLine("STUDIO CREATE: " + r);

			r = StudioSystem.Native.getCoreSystem(out CoreSystem.Native);
			Console.WriteLine("CORE SYSTEM: " + r);

			// This also will init core system. 
			StudioSystem.Native.initialize(maxChannels, studioInitFlags, coreInitFlags, (IntPtr)0);

Can you try the logging version of FMOD instead, you should get some information output on the TTY as to what is going wrong.

gn.fur · February 6, 2021, 3:41pm

Tried the logger library. This is what it outputted in the console (along with some dotnet stuff). There isn’t anything out of ordinary, it seems. I see some thread permission errors, tho. Running with sudo fixes them, but my game crashes anyway with same error.

According to your output I see:
PLAY RESULTS:ERR_INVALID_HANDLE | FMOD.Channel

However I don’t see any
LOAD RESULTS:

Also, in the log I don’t see any Sounds being loaded by FMOD, is it possible the load isn’t being called at all?

gn.fur · February 8, 2021, 10:23am

That’s because I don’t output them. Load results are OK. Besides, it works on both Windows and Android. I’ll doublecheck when I’ll get home.

mathew · February 9, 2021, 12:53am

Regardless of the LOAD RESULTS, there should also be logging from FMOD when you create a sound which appears to be missing unless you snipped it out of the log provided?

gn.fur · September 19, 2022, 12:53am

A year and a half later, I am finally returning to this problem. : D

Yes, it is indeed missing. The sound load logs appear when I use core-only mode - then everything works fine.
I have updated to the latest version of FMOD, the problem still persists.

gn.fur · September 19, 2022, 7:32pm

UPDATE: It seems I have found the solution? Or at least a fix that seems to do the job.

If I initialize Core system before the Studio system, both seem to work. I wasn’t initializing Core system at all in Studio mode, as far am I am aware, Studio system also inits Core system - and this seems to be the case on all other platforms.

FMOD.Factory.System_Create(out CoreSystem.Native);
FMOD.Studio.System.create(out StudioSystem.Native);

Could somebody from FMOD comment on this? Am I missing something here?

jeff_fmod · September 19, 2022, 11:24pm

There is a requirement when using C# to call into the Core API before calling FMOD.Studio.System.create. This is due to a limitation with dependency loading in the C# runtime.
Any call into the Core API would satisfy this criteria. In our Unity integration for example we call FMOD.Memory.GetStats as an innocuous and relatively low overhead way to meet this requirement. To confirm this is the issues can you please try calling FMOD.Memory.GetStats and see if that gives you the same result?

gn.fur · September 20, 2022, 11:25am

Yep. I replaced create with FMOD.Memory.GetStats(out var currentallocated, out var maxallocated); and got the same result. Thanks for the explanation.
