[Bug 2125641] Re: Auto switching audio to HDMI back and forth does not work anymore

 

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

I wasn't able to reproduce this behaviour on Questing nor on Plucky. My
test was,

1. Start playing music with laptop speakers.
2. Plug HDMI cable in, music automatically routed to HDMI.
3. Unplug HDMI cable, music automatically returns to laptop speakers.

The fix you referenced is shipped in Plucky,

 wireplumber | 0.4.8-4         | jammy/universe | source, amd64, arm64, armhf, ppc64el, riscv64, s390x
 wireplumber | 0.4.17-1ubuntu4 | noble          | source, amd64, arm64, armhf, ppc64el, riscv64, s390x
 wireplumber | 0.5.8-1         | plucky         | source, amd64, arm64, armhf, ppc64el, riscv64, s390x
 wireplumber | 0.5.10-3        | questing       | source, amd64, arm64, armhf, ppc64el, riscv64, s390x

Can you verify your local wireplumber configuration contains the fix
(you have the package version containing the fix, so you should?)

$ grep 'profile.name == profile_name' /usr/share/wireplumber/scripts/device/state-profile.lua
        if profile.name == profile_name and profile.available ~= "no" then

If not, we'll need to enable debug logging and try to see what is going
wrong on your setup.

Title:
  Auto switching audio to HDMI back and forth does not work anymore

Status in wireplumber package in Ubuntu:
  Incomplete

Bug description:
  It seems like Ubuntu 25.04's version of wireplumber has a bug
  (https://gitlab.freedesktop.org/pipewire/wireplumber/-/issues/613)
  where if you plug your laptop into a HDMI monitor and expect your
  audio to switch over, it will not. It seems like the bug has been
  there since 0.5.0 and 25.04 is the first version that officially
  releases with that version.

  This is kind of a problem for every day usage and will not be great if
  it is not fixed by the next LTS.

  Workaround: run the following command after switching to HDMI.

  systemctl --user restart wireplumber.service
