[UWP] Audio effect Dissonance Echo Cancellation could not be found

[Alexees]

@martindevans Just want to hook in on this for UWP in Unity 2018.2.6f1. I am receiving this error after upgrading from 6.2.4 to 6.2.6, or I have not noticed it at all since I have implemented it just recently. The size of the copied dll matches the x86 one, so it's the right one and avaiable. They are configured correctly in Unity. I even did a fresh import of the new dissonance package after deleting all the old files. I can try to revert back to 6.2.4 to see if it was recently introduced, but I doubt it. Update: same thing with 6.2.4. Trying empty project now Update: same thing happened again:

New Projekt with 2018.2.6f1, imported dissonance and HLAPI

• added AudioSource to scene referencing mixer with the echo cancelor and disabled audiomixer suspend
• building just that scene and launching it on the hololens shows this error of a missing dll that exists in the project

Is this deploying to the hololens, or just standard desktop UWP?

Could you check the import settings on the files in Assets/Plugins/Dissonance/Plugins/UWP, check that the two files (opus/AudioPluginDissonance) in the two folders (x86/x86_64) have import settings corresponding to their location.

[Alexees]

It's Hololens I'm testing this with at the moment. I double checked. Yes, they are both configured correctly.

[martindevans]

What's odd about this is that the AEC and the audio preprocessor are both in the same DLL. The preprocessor is critical to Dissonance so if that wasn't loading correctly nothing would work at all! It's obviously some kind of problem with the "automagic" Unity uses to load audio plugins. We've previously had other issues related to this (#91) but they should be resolved now.

Could you just sanity check that the DLLs are definitely the correct ones. Both in the editor itself, and also in the built application deployed to the hololens. Here are the expected file hashes (you'll be using the x86 ones on Hololens):

To me this looks correct, although they appear 3 times in the build

You do not seem to have the chance of debugging it in a hololens, do you? I can try with The Mixed Reality Portal as that's available to everyone and see if it happens there too. Update: Yap, same thing for the portal

[martindevans]

It looks like something went wrong last time I rebuilt the UWP plugin. The exported symbols from the x86 AudioPluginDissonance are:

1     0 00019600 Dissonance_ConfigureAecSuppression
2     1 000194B0 Dissonance_ConfigureNoiseSuppression
3     2 00018FC0 Dissonance_CreatePreprocessor
4     3 00019490 Dissonance_DestroyPreprocessor
5     4 0001A4F0 Dissonance_GetAecMetrics
6     5 0001A4E0 Dissonance_GetFilterState
7     6 00019710 Dissonance_GetVadSpeechState
8     7 000197B0 Dissonance_PreprocessCaptureFrame
9     8 0001A450 Dissonance_PreprocessorExchangeInstance
10    9 00018EA0 UnityGetAudioEffectDefinitions

The important one is the final one, that's how queries what audio filters to load from the DLL. The same output for the current UWP/x86/AudioPluginDissonance:

1    0 00001CF0 Dissonance_ConfigureAecSuppression
2    1 00001CB0 Dissonance_ConfigureNoiseSuppression
3    2 000019F0 Dissonance_CreatePreprocessor
4    3 00001C90 Dissonance_DestroyPreprocessor
5    4 00001120 Dissonance_GetAecMetrics
6    5 00001110 Dissonance_GetFilterState
7    6 00001D70 Dissonance_GetVadSpeechState
8    7 00001D90 Dissonance_PreprocessCaptureFrame
9    8 00001080 Dissonance_PreprocessorExchangeInstance

As you can see the UnityGetAudioEffectDefinitions function hasn't been exported, which means Unity thinks there are no filters in the DLL. Presumably I misconfigured the linker somehow.

If you email me (martin@placeholder-software.co.uk) your invoice number I'll send you back a fixed DLL as soon as I have one.

[martindevans]

I've modified the linker settings to explicitly export the UnityGetAudioEffectDefinitions symbol and I've also explicitly named the symbol to prevent C++ name mangling. The exports now look like this:

1     0 00002820 Dissonance_ConfigureAecSuppression = _Dissonance_ConfigureAecSuppression
2     1 000027E0 Dissonance_ConfigureNoiseSuppression = _Dissonance_ConfigureNoiseSuppression
3     2 00002530 Dissonance_CreatePreprocessor = _Dissonance_CreatePreprocessor
4     3 000027C0 Dissonance_DestroyPreprocessor = _Dissonance_DestroyPreprocessor
5     4 00001500 Dissonance_GetAecMetrics = _Dissonance_GetAecMetrics
6     5 000014F0 Dissonance_GetFilterState = _Dissonance_GetFilterState
7     6 000028A0 Dissonance_GetVadSpeechState = _Dissonance_GetVadSpeechState
8     7 000028C0 Dissonance_PreprocessCaptureFrame = _Dissonance_PreprocessCaptureFrame
9     8 00001460 Dissonance_PreprocessorExchangeInstance = _Dissonance_PreprocessorExchangeInstance
10    9 00001070 UnityGetAudioEffectDefinitions = _UnityGetAudioEffectDefinitions@4

As you can see all the Dissonance symbols are still there, and the UnityGetAudioEffectDefinitions symbol has been added without any mangling (i.e. @4). I've emailed you this DLL to try out.

@martindevans the problem is gone on the Hololens, thanks for the updated DLL. But it's also missing in the x64 dll which I need for the Mixed Reality Client.

[martindevans]

Thanks for checking that and confirming that it's fixed. I'll make the same changes to the 64 bit build now and send you the DLL once it's done :)

Edit: I've sent it

[Alexees]

Hey Martin, I looks like all the DLLs are broken. I've now run the project on OculusGO(Android) and the same error appeared. Could you just run through all of them and push an update or something?

[martindevans]

Is the error the same as #110 (Android AEC fails to load)? If so that's a Unity bug and we're waiting for a fix from them.

[Alexees]

jup, is. Waiting... :)

[martindevans]

Hey Alexees, did you see my latest post on the Android issue? According to Unity it's fixed, so hopefully that will fix your Oculus GO problem.

[martindevans]

Dissonance 6.3.0 just went live on the asset store, that version includes the rebuilt DLLs to fix this issue. I'll close this issue now, don't hesitate to re-open it if the problem persists :)
