New Drj projector connected to iPhone via HDMI to lightening adapter. Only getting sound with YouTube, home videos, and a couple of Netflix movies. Picture is fine. Not sure why sound works with some and not others. Please help or I’m returning it.
See if there is something in the settings of your phone to force your audio to be PCM rather than Dolby Digital. Your projector may not be able to decode Dolby Digital audio.
