Followed pattern set out by texture streaming so that each chunk of audio data resides in its own bulkdata struct. It is currently possible to split audio into chunks when SoundWaves are marked for streaming but there is no way of doing this exposed at present.
Changed the parameters of FAudioDevice::GetRuntimeFormat so that the relevant SoundWave must be passed in, to allow for different formats for individual sounds/streaming options.
USoundWave::FreeResources no longer resets the NumChannels as it is unnecessary and causes sounds to be unable to play after the OGG data is flushed when attempting to switch to OPUS.
