I'm not sure I believe that. If the chip has no S/PDIF output, then
there won't be an S/PDIF plug on the board, because there is no place to
solder the wires. That driver supports the LX, SX, and MX, but only the
MX has S/PDIF pins.

The pinouts on the two devices are the same. The two S/PDIF pins on the
PCM2906 are labeled "TEST0" and "TEST1" on the PCM2904. If you want to
experiment, you could try connecting an S/PDIF connector to the those
two pins and pretending it is a PCM2906, but I suspect the engineers at
TI are smarter than that.
