Using custom ambient sounds (dragging in a .wav file to the world) works fine on PC, but fails to play on PS4. Built in ones work fine on both platforms. Here’s a log entry from my PS4:
[2022.07.20-22.59.41:517][257]LogAudioMixer: Warning: FMixerBuffer::CreateStreamingBuffer failed to StreamCompressedInfo on SoundWave ‘Test_Audio’. Invalidating wave resource data (asset now requires re-cook).
