Yes, definitely, at the end, I don't see an option other than RTFM.
Documentation : I could insert a "dolby_e" section between ac3 and flac in decoders.texi.
But there is nothing specific to dolby_e for real.
Maybe an overall "stream probing" chapter would be better in decoders.texi between "Decoders" and "Video Decoders" chapters; with a specific paragraph about the non_pcm_mode option for wav/s337 (and later for s302) ?
