Eu tenho um conector de áudio danificado que fica conectado por uma fração de segundo a cada poucos segundos. Isso faz com que um som de estalidos fraco ocorra quando a saída é comutada para os fones de ouvido e depois para trás.
O que funcionou antes foi remover o módulo-switch-on-port-available do /etc/pulse/default.pa. Desde que eu atualizei para o Ubuntu 18.04 de 16.04 isso não funciona mais. O módulo não é carregado quando você verifica o pactl, mas a saída continua mudando.
Eu tentei muitas coisas, mas nada parece funcionar. Eu até desabilitei os fones removendo os arquivos de configuração em alsa-mixer / paths. De fato, quando eu conecto os fones de ouvido, eles não funcionam. Mas o som crepitante ainda está lá quando eu os desconecto. Os registros de áudio de pulsos continuam dizendo:

Lineout é a saída que desejo usar. Qualquer idéia sobre como parar a comutação ou desativar a porta do fone de ouvido.
