• Bug#1106198: pipewire keeps changing volume of output device

    From Jonathan Kamens@21:1/5 to All on Wed May 21 03:00:01 2025
    Package: pipewire
    Version: 1.4.2-1
    Severity: normal

    Every time I unplug my DisplayLink hub from my main desktop, pipewire
    changes the volume of my built-in audio device:

    id 52, type PipeWire:Interface:Device/3
    object.serial = "53"
    factory.id = "15"
    client.id = "47"
    device.api = "alsa"
    device.description = "Built-in Audio"
    device.name = "alsa_card.pci-0000_00_1f.3"
    device.nick = "HDA Intel PCH"
    media.class = "Audio/Device"

    Just to be clear, *this is not a device plugged into the DisplayLink
    hub*, it's built into my motherboard.

    This is new behavior. It's incredibly annoying.

    Why this matters: I have the output volume of this device muted nearly
    all the time. When I unplug my DisplayLink hub to plug it into and
    user a different computer, I don't want apps on my main desktop to
    make noise, but they start making noise as soon as I unplug the hub,
    because pipewire messes with the volume.

    It didn't always do this, this seems to have broken relatively
    recently.
