I’m not exactly sure what you mean.
Most of the DAC boards that are discussed here on this forum are supported out of the box by Volumio and can be enabled using tue WebUI - no need to edit config.txt or to install drivers.
If you are looking for a cheap DAC with the least possible configuration needed I’d recommend the Hifiberry DAC+ (costs around 35€ in Germany). You can flash its EEPROM once and use the DAC on every OS with a halfway recent Kernel without the need for configuration or even a reboot. See this blog entry: hifiberry.com/blog/flash-yo … iguration/
I tested this with my DAC+ Pro and it worked fine in LibreELEC - I could use the DAC+ Pro from first boot.
