Wireplumber set media role on a sink stream [SOLVED]

I want to use pipewire's ducking feature to suppress the background sounds in event of notfication.
from what i could find, pipewire does this automatically if there is a media role higher than other input streams.

I used `play` command from `sox` package to play a wav file, and on checking the stream info using `pw-cli info all` it seems like that it has no such role.
i cant figure out how to assign this role to manual streams, from what examples i could find, this is hardcoded in apps.

please help me getting this to work

Re: Wireplumber set media role on a sink stream [SOLVED]

I use `play` command from `Sox` package to play a wav file along with notifications.
now that pipewire has removed the ducking module, and replaced it with behaviour of ducking other sounds when a stream of media has property `media.role` is of higher privilege than most.

so using pipewire config, i was trying to assign this property to streams produced by sox package.

.config/wireplumber/wireplumber.conf.d/60-role.conf

monitor.alsa.rules = [
  {
    matches = [
      {
        node.name = "SoX"
      }
    ]
    actions = {
      update-props = {
        media.role = "Music",
      }
    }
  }
]

but it doesnt have any effect whatsoever.
I tried to look into documentation, but no avail, setting it via this method seems to be only solution but its not working when i play sound using play command, and check info via `pw-cli info all`
property `media.role` is always absent from it

any clue on what the issue is, or what i can do to get the desired behaviour

Re: Wireplumber set media role on a sink stream [SOLVED]

https://pipewire.pages.freedesktop.org/ … ccess.html contains the gist of it, you can listen to a certain client connecting and update prop the media.role

Also please don't crosspost, you basically created a new thread for the same issue.

Merging...

As for the attempt you had, alsa rules are for device rules, access rules for client rules, that's likely the relevant difference.

Re: Wireplumber set media role on a sink stream [SOLVED]

thanks for replying, sorry about the crossposting, i realized it later that it would be more relevant here

So i modified the file `$HOME/.config/wireplumber/wireplumber.conf.d/60-role.conf`

access.rules = [
  {
    matches = [
      {
        node.name = "SoX"
      }
    ]
    actions = {
      update-props = {
        default_permissions = "all",
        media.role = "Music",
        node.nick = "My Node"
      }
    }
  }
]

still no change which is desired

Re: Wireplumber set media role on a sink stream [SOLVED]

you restarted wireplumber after the change? You are sure SoX is the correct node.name?

Re: Wireplumber set media role on a sink stream [SOLVED]

yea i restarted wireplumber and pipewire both, and I tried with both settings, application.name and node.name from info dump i got from ` pw-cli info all `

*	properties:
*		client.api = "pipewire-pulse"
*		pulse.server.type = "unix"
*		application.name = "SoX"
*		application.process.id = "695581"
*		application.process.user = "kushy"
*		application.process.host = "kushy-pc"
*		application.process.binary = "sox"
*		application.language = "C"
*		window.x11.display = ":0"
*		application.process.machine-id = "5915f7aa3d9b455fb1a29b84c08c3e7b"
*		application.process.session-id = "56"
*		media.name = "playback"
*		node.rate = "1/44100"
*		node.latency = "4630/44100"
*		stream.is-live = "true"
*		node.name = "SoX"
*		media.class = "Stream/Output/Audio"
