Very nice! So if we publish an IOAudioStream format with the Dolby sample format, what will we get in our clip call? Will it be Dolby encoded audio data? I ask this because PCM formats arrive as floats so we do have to do some conversion. I'm wondering what type of conversion (if any) is needed for Dolby?
