Sound settings not saved across reboots

[T13nou]

Describe the bug

Hi !

I've got my HTPC running Bazzite pretty well but I need to set the sound device at each reboot. I'm using audio thru HDMI as my HTPC is connected to the TV.

When I go to Settings > Audio, I have 3 options

• Default (auto)
• Internal Audio
• Navi31 HDMI/DP Audio

The settings I'm using is the Navi31 HDMI as my HTPC is connected to the TV and renders video & sound thru it.

At each reboot, default (auto) is selected and I need to set again Navi31 HDMI/DP manually.

What did you expect to happen?

That the settings I choose manually keeps the same across reboots.

Output of rpm-ostree status

This is expected behavior, Steam game mode will always default to the output set by Wireplumber. If you need to change that default you need to modify your configs.

Thanks @KyleGospo ! Can you please explain how could I do that ?

  {
    matches = [
      {
        node.name = "~alsa_input.*"
        alsa.card_name = "Wireless Controller"
      }
      {
        node.name = "~alsa_output.*"
        alsa.card_name = "Wireless Controller"
      }
    ]
    actions = {
      update-props = {
        priority.driver        = 90
        priority.session       = 90
      }
    }
  }
]

Here's an example config that lowers the priority of a given output.
By changing the priority to be the highest (Get your list of outputs and their priorities with pactl list sinks), you will change the default selected audio output. That same command will also list the various properties you can use to match your desired output.

Thanks @KyleGospo :) Not sure about where to find this config file and how to change it. Any guidance ?

Thanks !
