Steam Audio

I can’t test it deeply right now, but this should fix it:

PhononPluginManager.cpp

void FPhononPluginManager::OnListenerShutdown(FAudioDevice* AudioDevice)
{
 // Shutdown reverb effect
if (IsUsingSteamAudioPlugin(EAudioPlugin::REVERB))
{
ReverbPtr = static_cast<FPhononReverb*>(AudioDevice->ReverbPluginInterface.Get());
ReverbPtr->DestroyReverbEffect();
ReverbPtr->Shutdown();
}

FSteamAudioModule* Module = &FModuleManager::GetModuleChecked<FSteamAudioModule>("SteamAudio");
if (Module != nullptr)
{
Module->UnregisterAudioDevice(AudioDevice);
}
}

PhononReverb.cpp

void FPhononReverb::Shutdown()
{
for (auto& ReverbSource : ReverbSources)
{
if (ReverbSource.ConvolutionEffect)
{
iplDestroyConvolutionEffect(&ReverbSource.ConvolutionEffect);
}
}

if (ReverbConvolutionEffect)
{
iplDestroyConvolutionEffect(&ReverbConvolutionEffect);
}

if (IndirectBinauralEffect)
{
iplDestroyAmbisonicsBinauralEffect(&IndirectBinauralEffect);
}

if (IndirectPanningEffect)
{
iplDestroyAmbisonicsPanningEffect(&IndirectPanningEffect);
}

if (BinauralRenderer)
{
iplDestroyBinauralRenderer(&BinauralRenderer);
}

if (IndirectOutDeinterleaved)
{
for (int32 i = 0; i < AmbisonicsChannels; ++i)
{
delete] IndirectOutDeinterleaved*;
}
delete] IndirectOutDeinterleaved;
IndirectOutDeinterleaved = nullptr;
}

Environment = nullptr;
}

void FPhononReverb::DestroyReverbEffect()
{
for (FReverbSource& ReverbSource : ReverbSources)
{
if (ReverbSource.ConvolutionEffect)
{
iplDestroyConvolutionEffect(&ReverbSource.ConvolutionEffect);
}
}
}

And to be safe:

void FPhononReverb::SetEnvironment(FEnvironment* InEnvironment)
{
if (!InEnvironment)
{
return;
}

 // Free currently existing environment
if (Environment)
{
// Shutdown all
DestroyReverbEffect();
Shutdown();
}

...
}

Thanks, I will let you know if problem still persists after this change.
