pulseaudio.service “Falha ao iniciar o serviço de som.”

Question

Na minha área de trabalho, recebo vários erros relacionados a pulseaudio em journalctl após a inicialização:

Por que esses problemas aparecem? Isso é algo para se preocupar?

Eu não percebi isso antes, porque o som está tocando e os ícones de volume também funcionam.

Estou executando o Manjaro ( 4.17.0-2-MANJARO ) com i3wm e pulseaudio 11.1 .
