[Andrew]’s original broader plan was to pipe the S/PDIF data to the onboard I2S DAC, though he struggled manipulating the remaining resources on the STM chip to do so successfully. Anyone ...

The DAC also uses DSD Remastering to improve the ... 4.4mm and 3.5mm inputs alongside USB-C and a combined optical/coaxial S/PDIF input. There's also a balanced 4.4mm, twin 3.5mm and a single ...

S/PDIF, and more specifically optical TOSLINK, uses LED light sent down an optical fiber to encode audio data. The advantage of this over any voltage-level signals (like with regular wires ...
