I just tag one MP3 file to “Audiobook” and copy it to the root of the SD card. It still does not show up in Audiobook.
I have tried using ID3v1.1 and ID3v2.3. I tried using “Audiobook”, “Audiobooks”, “AUDIOBOOK”, “Podcast” and nothing shows up. I tried copy to internal memory or SD card.
I looked at the Genre and can never find the “Audiobook” tag.
Don’t understand why it does not work.
