I have a new Mac mini 2018. I want to get surround sound over HDMI.
I have a receiver that is capable of transmitting 5.1 surround sound to my speakers, and HDMI video to my projector. I have confirmed that this is possible using alternative hardware (e.g. Windows PC).
When I connect my Mac mini to the receiver, I get video to the projector and sound to the speakers. However, the sound is only 2 channel stereo.
I have tried using the
Audio MIDI Setup app to configure the audio. I can choose
5.1 Surround as speaker configuration, but when I test that setup, sound is only output through the two front stereo speakers.
Strangely, the Audio MDID Setup app identifies my audio as
DisplayPort, even though it should be HDMI.
Output tab of Sound settings, the port is also shown as DisplayPort, no other options available
Also a bit strange, in the
Sound Effects tab of the Sound settings, I can choose
EPSON PJ for
Play sound effects through, but
Output volume is disabled.
I am running the currently latest macOS, Mojave 10.14.1. My receiver is a SONY STR-DN1040 AV-receiver. My projector is an Epson EH-TW9200
