Deixe-me começar por esclarecer que a saída de áudio da minha tomada estéreo é detectada / listada como um dispositivo IEC958 / S/PDIF , mas não é uma saída óptica, é uma tomada estéreo padrão. Isso pode já ser a causa do problema.
Na detecção de conexão / desconexão do Windows funciona bem, e funcionou antes no linux (usando o Mint 4.10.0-35-generic) mas em outros WMs, atualmente usando i3 , mas eu acho que não está relacionado ao WM, e outra coisa poderia ter mudado nesse meio tempo. Não me lembro de instalar nenhum driver para o áudio, ele já funcionou.
O problema
Não consigo disparar o evento de plug-in / desconectar o conector de áudio.
O que funciona
Alternar manualmente com pavucontrol para saída de estéreo digital (IEC958) ( iec985-stereo-output ) silenciará meus alto-falantes ( analog-output-speaker ) e fornecerá controle de volume e áudio no conector. Bom.
Não há outra opção na lista que ofereça o áudio exclusivo do meu conector (assim, os alto-falantes são silenciados). (Além deste outro problema que eu estava lidando com primeiro, até que eu descobri que eu tinha que mudar para a saída IEC958 : O volume de áudio vai de 0 a 100 em aux (basicamente apenas ligado / desligado) & link mas isso é um buraco de coelho completamente diferente para ir para baixo, mas de qualquer maneira.

Mas para o microfone:

diff events
Pelo que entendi, podemos zombar dos eventos com:
sudo cat /proc/asound/card0/codec\#0 > unplugged
sudo cat /proc/asound/card0/codec\#0 > plugged
diff unplugged plugged
Mas o diff não produz nada.
