I am trying to configure PipeWire to use my sound card’s digital output. Audio works via the PC’s line-out jack, but not the S/PDIF optical port. This is the expected default configuration, but I am trying to enable the digital output.
ALSA appears to detect the capability for digital output:
[faokryn@localhost ~]$ aplay -l

but PipeWire/WirePlumber only has an “Analog Stereo” version of “Built-in Audio”:

I can’t seem to find information on how to get WirePlumber to detect and use this profile- basically the equivalent of pactl --set-card-profile with PulseAudio.
Can anyone advise me or point me in the right direction? Thanks
