Bonjour,
j’aimerais pouvoir, via PulseAudio, écouter de la musique sur ma chaîne Hi-Fi via la prise jack de mon PC, tout en ayant les autres sons sur les enceintes de mon PC. PulseAudio le faisait très bien sur mon ancien PC, considérant qu’il y avait deux cartes son.
Sur mon PC actuel, il n’en voit qu’une avec deux ports, et je ne peux que passer de l’un à l’autre. J’aimerais utiliser les deux en même temps avec des flux audios différents.
Voici le résultat de list-sinks avec pacmd :

La deuxième carte, « Mono » est une carte virtuelle permettant de fusionner les channels afin d’avoir une sortie mono, que j’utilise quand je ne mets qu’un écouteur.
Merci, Breizh.
