Micca OriGen no signal from optical S/PDIF output

The OriGen’s 3.5mm jack also doubles as a optical mini output jack. When it is working, the jack will glow red indicating that a signal is present. While this output will work for most situations, there are three known limitation with the optical S/PDIF output where it will not produce any output:

  • If the PCM signal is 32-bit 192kHz as this exceeds optical specifications. The limit is 24-bit 192kHz.
  • If the output mode is ASIO. The VIA USB chip only supports S/PDIF output when the data stream is Direct Sound or WASAPI.
  • When used with certain Android phones over USB OTG, since certain Android implementations lack the necessary endpoint support for S/PDIF output.
