Raspberry Pi4 with Volumio is a simple as it gets.  For digital output try the Pi2AES card or Allo Digital DigiOne or DigiOne Signature.

I have given Raspberry Pi based systems much consideration over the last year. I was originally set on the USBridge Signature (Pi 3B+ CM) with the DigiOne Signature HAT and Graham's DAK 5V 3A power supply. However, I did not want to invest lots of money into a computer that is limited by operating system, graphics quality and processing power. I wanted the choice to be more versatile and instead looked into single board computers with x86/x64 based architecture capable of running Windows if I wanted and with high quality sound/graphics options, even being able to connect/program some Pi-HATs to work if I wanted. Enter Hackboard 2, the budget mixture product. Not going to bother with the DigiOne Signature now I already have a Pink Faun PCIe S/PDIF card, as I can implement the Pink Faun with any computer system that provides hardware access to the PCIe bus and the power connection options on the PCIe card are better than on the HAT. I can even upgrade the clock and change the output connector board and fixing bracket if I want. Very few more powerful computers offer access to a Pi-compatible 40-GPIO layout so a £225 spend on the DigiOne Signature would be less versatile and with some operating systems, will require some additional programming to get working. I can still implement Graham's DAK supply for the card but will need an extra 12V LPSU for the computer, which will set me up for future-12V low power x86/x84 computers.

Question... Reckon I could use my motherboard S/PDIF header bracket as a coaxial to optical converter? My Pink Faun card is dual coaxial output so imagine if I could convert one connection to optical so I have the option of either. The SPDIF pin of the three pin header would normally take the electrical signal from the motherboard to both types of digital output simultaneously meaning they are joined to each other by a continuous track. The +5V and GND pins would allow use of a 5V linear power supply to power the LED. There are a few small components on the board that I assume are resistors. As long as there are no diodes or transistors in the SPDIF path, there should be no bias or directionality so I can connect the coax out as a coax in?
