[SOLVED]Wireplumber config seems doesn't used.

I'm trying to combine 2 sound cards(onboard and usb soundbar) as a virtual device, but seems that the config file doesn't used.
I searched about it and I found a pipewire example which I configured it and put it to ~/.config/wireplumber/wireplumber.conf.d/combined-cards.conf.
These are the file contents:

context.modules = [
{   name = libpipewire-module-combine-stream
    args = {
        combine.mode = source
        node.name = "combine_source_4_0"
        node.description = "My 4.0 Combine Source"
        combine.latency-compensate = false
        combine.props = {
            audio.position = [ FL FR SL SR ]
        }
        stream.props = {
                stream.dont-remix = true
        }
        stream.rules = [
            {   matches = [
                    {   media.class = "Audio/Source"
                        node.name = "alsa_card.usb-Creative_Technology_Ltd_Sound_Blaster_GS3_1120041A00040504-01"
                    } ]
                actions = { create-stream = {
                        audio.position = [ FL FR ]
                        combine.audio.position = [ FL FR ]
                } } }
            {   matches = [
                    {   media.class = "Audio/Source"
                        node.name = "alsa_card.pci-0000_0a_00.4"
                    } ]
                actions = { create-stream = {
                        audio.position = [ FL FR ]
                        combine.audio.position = [ SL SR ]
                } } }
        ]
    }
}
]

With this I expected to created a virtual device but there is nothing in pavucontrol. I restarted the wireplumber service and also tried to logout/re-login, but I cannot see the virtual device, so I suppose that the config file doesn't load.

W/o any close look: your system is up-to-date?

Yes, latest update today before tried to configure the cards.

After a lot of search and trial and error I found a solution. At first, the soundbar doesn't have an input and I couldn't use source. I changed it to Sink and also I needed to use RL and RR instead of SL SR, to work and play sound both speakers. Also I used pipewire.conf.d instead of wireplumber because with wireplumber.conf.d the combine sink didn't created at all.
Here is my working conf file:

context.modules = [
  {
    name = libpipewire-module-combine-stream
    args = {
      combine.mode = sink
      node.name = "combined-sink"
      node.description = "My 4.0 Combined Sink"
      combine.props = {
        audio.position = [ FL FR SL SR ]
      }
      stream.props = {
        stream.dont-remix = true
      }
      stream.rules = [
        {
          matches = [
            {
              media.class = "Audio/Sink"
              node.name = "alsa_output.usb-Creative_Technology_Ltd_Sound_Blaster_GS3_1120041A00040504-01.analog-stereo"
            }
          ]
          actions = {
            create-stream = {
              audio.position = [ FL FR ]
              combine.audio.position = [ FL FR ]
            }
          }
        },
        {
          matches = [
            {
              media.class = "Audio/Sink"
              node.name = "alsa_output.pci-0000_0a_00.4.analog-stereo"
            }
          ]
          actions = {
            create-stream = {
              audio.position = [ FL FR ]
              combine.audio.position = [ RL RR ]
            }
          }
        }
      ]
    }
  }
