My Mn Cast works just fine with stereo output, but I’d like to switch over to Optical SPDIF.
I go into the web interface, and in the Audio tab I change from “I2SDAC” to “SPDIF” and reboot.
The Mn Cast starts up. I hit the play button in my LMS control page for the player. The red LED glows. But nothing comes through on my A/V receiver. I’ve got another Optical SPDIF device, and confirmed that the cabling and the Optical input of my receiver are working. I see red light coming out of the cable I’ve got plugged into the Mn Cast.
I see that others with a working implementation see “SP/DIF” in their ESP32 web interface
after they switch over. I don’t.
I’ve updated to the most recent version of firmware, I2S-4MFlash.16.2.1306.master-v4.
I’ve confirmed that the SPDIF options are bck 5, ws 25, do 4 as per a properly loaded NVS Config.
What more can I try?
