[SOLVED] "Output is set to HDMI but no audio device was detected on the HDMI port."

[rph-r]

Sorry. I had a mental lapse there   
I assume you mean an Audiophonics I2S device.

Same here, it is I2S indeed.
It was selected (ES9038). I selected another and reselected it, rebooted, and it is working now!
Since I already had trouble with the loss of device config due to empty config.txt I haven't thought to tweak in this config.

But I really don't know why the config changed.
Thank you for your help!!
