[RESOLU] Jack refuse de fonctionner avec Alsa (mais fonctionne en dummy)
je suis sur Ubuntu 16.04, sur un Gigabyte Brix GB-BPCE-3455 (CPU Intel J3455 Quad Core 1.5 Ghz).
J'utilise la sortie audio jack 3.5.
Ma config de base marche nickel avec pulseaudio
Si je fais un paplay, le son joue

Maintenant, je descends pulseaudio (pulseaudio --kill avec autospawn = no dans /etc/pulse/client.conf).
