The tuning host loaded module-rt with default arguments, so it asked for realtime through xdg-desktop-portal. A portal started before rtkit was installed reports a realtime budget of zero. module-rt applies that as a hard RLIMIT_RTTIME of 0, RTKit still makes the data thread SCHED_RR, and the kernel kills the host with SIGKILL as soon as audio plays; systemd restarts it every two seconds and the speakers stay silent until the next login. Set rtportal.enabled = false, as the stock pipewire.conf does. The host is a user service in the same session as the PipeWire daemon and has no reason to go through the portal. The host config is only copied by `omarchy-audio-tuning on`, so a migration replaces an installed copy that is still Omarchy's own with the old setting, and restarts the host if it runs. It does not call `on`, which would overwrite a tuning graph another tool wrote under the same name. Co-authored-by: Michael de By <contact@michaeldeby.nl>
