    Thanks for the report. I prepared a Flathub test build with a fix for the login/startup race where Mini EQ could start before PipeWire/WirePlumber had made the requested output sink available, then exit before enabling system-wide EQ.

    You do not need to uninstall 0.8.3. This installs the Flathub test branch, so it can be tested separately from the stable branch:

    flatpak install --user https://dl.flathub.org/build-repo/287237/io.github.bhack.mini-eq.flatpakref
flatpak run --branch=test io.github.bhack.mini-eq

    In the test build, please enable:

    • Keep Running in Background
    • Start at Login
    • Enable System-wide EQ at Login

    If those were already enabled in 0.8.3, please toggle Start at Login off and back on once from the test build, so the login autostart entry is refreshed for the test branch. Then reboot and check whether system-wide EQ comes back enabled automatically.

    The draft Flathub PR/test build is here:
    flathub/io.github.bhack.mini-eq#27

    After testing, the temporary test branch can be removed with:

    flatpak uninstall --user io.github.bhack.mini-eq//test

    If this fixes the issue for you, I will include it in the next release and update the stable Flathub package.

    Hi @bhack, thanks a lot for the quick response.

    I disabled "Start at Login" from the 0.8.3 version and enabled it in the test version and rebooted 6 times. System-wide EQ was enabled 2 out of those 6 times.

    I also notice that the command line added for the startup configuration for the test version does not include --branch=test, I'm not sure if it's an issue.

    I manually modified ~/.config/autostart/io.github.bhack.mini-eq.desktop to use the test version and I removed the background flag so that the test version is immediately visible, but the System-wide EQ is still unchecked :(

    Exec=flatpak run --branch=test --command=mini-eq io.github.bhack.mini-eq --auto-route

    When I disable autostart and start MiniEQ manually with flatpak run --branch=test --command=mini-eq io.github.bhack.mini-eq --auto-route it works so I think you're right it seems to be a race condition.

    The result you saw was most likely still from the earlier test build.

    I pushed an amended fix and Flathub has now built a new test build: 287257.

    Could you please install this one and retry the reboot test?

    flatpak install --user -y https://dl.flathub.org/build-repo/287257/io.github.bhack.mini-eq.flatpakref

    You do not need to uninstall 0.8.3; this installs/updates only the Flathub test branch, separate from the stable branch.

    You can keep the autostart command you tested manually:

    Exec=flatpak run --branch=test --command=mini-eq io.github.bhack.mini-eq --auto-route

    I also tested this new build locally in a Fedora GNOME VM with an artificial 15-second WirePlumber startup delay. With build 287257, Mini EQ started at login and the System-wide EQ switch came up enabled after reboot.

    If it still fails on your machine with 287257, then the remaining race is probably later in the final startup routing attempt, and I’ll add a second bounded retry around that path.

    I installed the new build but the switch is still disabled after a reboot :(
    Are there any log files I could provide that would be helpful?

    That confirms the new build still misses one startup path on your machine.

    Could you please capture these right after a reboot where the switch is still disabled, before starting/toggling Mini EQ manually?

    flatpak info io.github.bhack.mini-eq//test
cat ~/.config/autostart/io.github.bhack.mini-eq.desktop
gdbus call --session \
  --dest io.github.bhack.mini-eq \
  --object-path /io/github/bhack/mini_eq/Control \
  --method io.github.bhack.MiniEq.Control.GetState
journalctl --user -b --no-pager | grep -iE "mini-eq|pipewire|wireplumber|filter-chain|xdg-desktop-portal|background"
wpctl status
pw-link -l

    The most useful part is the journal from the same boot where it failed.

    This result also points to the remaining race being later than the first fix: Mini EQ can start, but the final startup --auto-route attempt may run before PipeWire/WirePlumber is ready to move streams. I’ll prepare a new build that retries that final startup routing attempt for a short bounded window as well.

    This confirms the remaining startup path in build 287257: Mini EQ is running and the filter-chain becomes ready, but the final startup --auto-route attempt does not retry, so the state stays routed: false.

    I prepared a newer test build with the second bounded retry around that final startup routing step:

    flatpak install --user -y https://dl.flathub.org/build-repo/287264/io.github.bhack.mini-eq.flatpakref

    Please retry with build 287264. You do not need to uninstall 0.8.3; this updates only the test branch.

    Your autostart command is fine for this test:

    Exec=flatpak run --branch=test --command=mini-eq io.github.bhack.mini-eq --auto-route

    I also reran this locally in the Fedora GNOME VM with an explicit 15-second WirePlumber startup delay. With build 287264, after reboot Mini EQ came up with eq_enabled: true and routed: true, and a playback stream was linked through mini_eq_sink.

    It works! I rebooted 3 times and for all 3 reboots the app starts, for a brief moment the switch is off then it is toggled on automatically. Thank you 😄

    Great, that confirms build 287264 covers the startup race on your system as well.

    I’ll include this fix in the next release and then update the stable Flathub package.
