Many special device settings and features in moOde like Hardware volume or Chip options are made available based on selecting the "Named device" and not the "DT overlay".
Also some chip options are only available if the device itself has a custom proprietary microcontroller interface to the DAC chip. There is no mention of an interfacing microcontroller on the board in question.
Here are the chip options for the Audiophonics ES9038 DAC which contains an Audiophonics proprietary custom microcontroller interface to the ESS chip. In pictures its the giant Altera FPGA chip. My particular device is the RaspiDAC Mini product.
Input select.....................Oversampling filter
The Boss 2 DAC has two mixers. The main PCM mixer is named "Master" and the DoP mixer is named "Digital". moOde assigns "Master" as the PCM mixer based on the "Named device" and not the "DT overlay". The device name is also used to enable auto-start of Boss 2 OLED display and to keep Master and Digital mixers in sync.
