Audio Device Play StartTime is getting ignored because of empty cooked data #26

Hello, i'm trying to play an imported sound wave per AudioDevice->Play(some start time) but the start time is always getting ignored and the sound playback starts at 0.0

As far as i can see it's because of

USoundWave::CookedSpectralTimeData and USoundWave::CookedEnvelopeTimeData being empty in USoundWave::GetSoundWavesWithCookedAnalysisData

Called from UAudioComponent::PlayInternal

// Setup audio component cooked analysis data playback data set if (AudioDevice->IsBakedAnalaysisQueryingEnabled()) { TArray<USoundWave*> SoundWavesWithCookedData; NewActiveSound.bUpdatePlaybackTime = Sound->GetSoundWavesWithCookedAnalysisData(SoundWavesWithCookedData);

bUpdatePlaybackTime will be false, resulting in FActiveSound::UpdateWaveInstances not updating the playback time.

I'm importing the audio from a buffer transmitted per network using URuntimeAudioImporterLibrary::ImportAudioFromBuffer (Audio works perfect besides the start time) RuntimeAudioImporter->ImportAudioFromBuffer(track.Buffer, EAudioFormat::OggVorbis)

Should have read the documentation.
