SINTOMA
Não ouço nenhum som.
Nas configurações dos aplicativos, guia Som, posso selecionar estes dispositivos:
Porta HDMI / Display - Áudio Integrado
Saída Digital (S/PDIF) - Áudio Integrado
Fones de ouvido - Áudio integrado
Saída fictícia
Quando clico em TEST em qualquer um deles, não há alto-falantes em que possa clicar. Espero que um botão ESQUERDO e DIREITO apareça.
ATUALIZAÇÃO 1
Quando inicio o pulseaudio na linha de comando, no modo detalhado, ele termina rapidamente, após alguns segundos com:
I: [pulseaudio] core.c: We are idle, quitting...
I: [pulseaudio] main.c: Daemon shutdown initiated.
Iniciando o pulseaudio com um tempo limite de inatividade maior, obtém-se o mesmo resultado: sem saída de áudio, sem alto-falantes na caixa de diálogo.
ATUALIZAÇÃO 2
Quando esse problema acontece, uma reinicialização o corrige temporariamente.
Tentei acionar o problema após uma reinicialização com um ciclo de suspensão/despertar, mas depois de acordar, o som ainda funcionava. Portanto, é preciso mais do que uma suspensão para ativá-lo.
