Even Sox plays (and gets its wires made):

$ play -n synth sine 440

The linkage looks like:

$ pw-link -l
alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX0
  |<- ALSA plug-in [sox]:output_FL
alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX1
  |<- ALSA plug-in [sox]:output_FR
ALSA plug-in [sox]:output_FL
  |-> alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX0
ALSA plug-in [sox]:output_FR
  |-> alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX1

Which is hardly different to the links I make manually for jack-play:

$ jack-play -u a48k.wav

$ pw-link -l
alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX0
  |<- jack-play:out_1
alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX1
  |<- jack-play:out_2
jack-play:out_1
  |-> alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX0
jack-play:out_2
  |-> alsa_output.usb-EDIROL_M-16DX-00.pro-output-0:playback_AUX1

But I do see that the connecting links show up dotted in Helvium.

pw-play works, of course, but has no jack_transport awareness option.

Could someone with Pipewire just test that jack-play doesn't play for them
either (without going via a meterbridge) before I post it as a bug?
