Timidity работает и загружает одно ядро моего процессора

Уже дважды (с некоторым промежутком, думаю, в несколько недель) Timidity начинался из ниоткуда, когда я запускал свой компьютер из спящего режима. Он занимает всю вычислительную мощность одного из моих ядер и работает уже около 5-10 минут, и мне хотелось бы узнать, почему запускается этот процесс.

Запуск pstreeпоказывает, что процесс является прямым потомком , systemdпоэтому я предполагаю, systemdчто он отвечает за запуск timidity, но я не знаю, как найти конфигурацию, которая запустилась timidity.

Если я запущу straceэтот процесс, то получу следующее:

Файлы, открываемые этим процессом:

/dev/null
/dev/snd/timer
/dev/snd/pcmC0D0p
/dev/snd/controlC0
/dev/snd/seq

Запущенная командная строка выглядит так:

/usr/bin/timidity-Os-iAD

Последние 3 информации взяты из /proc/$PID/.

Поэтому я спрашиваю, как мне узнать, почему timidityон запускается (позже я займусь проблемой, почему он занимает все ядра).
