Preventing Pipewire from being SIGKILLed
lantian.pub/en/article/random-notes/pipewire-sigkill-fix.lantianI frequently encounter the situation that the Pipewire audio server is suddenly stopped:
The problem usually appears when I connect/disconnect my laptop from the power adapter. My computer usually lags for a short time while switching between performance profiles.
systemctl --user status pipewire.service only shows that the Pipewire process was terminated by a SIGKILL signal, without any other useful log information.
Neither coredumpctl nor dmesg shows the existence of a core dump event.
