Bug description:
  Ubuntu 24.04 noble

  I tested on Kernel-6.7.2, 6.7.1, 6.6.8, don't work.

  relating service status:
   
  gsd-media-keys[6441]: gvc_mixer_card_get_index: assertion 'GVC_IS_MIXER_CARD (card)' failed

  pipewire-pulse[5768]: mod.protocol-pulse: client 0x5e701af4f9a0 [Mutter]: ERROR command:-1 (invalid) tag:418 error:25 (Input/output error)

  pipewire-pulse[5298]: default: snap_get_audio_permissions: failed to get the AppArmor info.

  wireplumber[61568]: <WpSiStandardLink:0x6289464187e0> si-standard-link: in/out items are not valid anymore
  wireplumber[61568]: <WpSiStandardLink:0x6289464541c0> 2 of 2 PipeWire links failed to activate

  It's worked on kernel linux-image-6.5.0-14-generic.

  I built the same version 1.0.1 from the
  https://gitlab.freedesktop.org/pipewire source code, The sound card
  can be detected normally and shown in the gnome setting.
