Cela semble être un problème avec pulseaudio. J'étais connecté par VNC sur mon téléphone et j'ai commencé à lire une vidéo, ce qui a fait planter X (comme cela arrive parfois). J'ai redémarré et soudain le son ne fonctionne plus.
-
J'ai un Intel HDA/Realtek ALC889
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller
-
alsamixer
le détecte très bien. -
PulseAudio ne détecte pas ce périphérique alsa et utilise donc
auto_null
comme évier par défaut (logs ci-dessous). -
Lorsque je tue correctement PulseAudio (en lui disant de ne pas se lancer automatiquement), la communication ALSA directe avec la carte son fonctionne parfaitement.
speaker-test
par exemple, fonctionne. Donc, les couches matérielles et ALSA sont bonnes, selon l'IMO. -
Dans les journaux, il semble que la carte soit "occupée", mais je ne sais vraiment pas comment ni pourquoi elle le serait maintenant (et jamais auparavant). Y a-t-il un fichier de verrouillage ALSA quelque part qui est toujours là à cause de mon crash ?

J'ai juste couru
sudo fuser /dev/snd/*
et j'ai vu ça :oli@bert:~$ sudo fuser /dev/snd/* /dev/snd/controlC0: 1884 /dev/snd/pcmC0D0c: 1884m /dev/snd/timer: 1884
Un coup d'œil à la liste des processus (
ps aux | grep 1884
) me dit que le processus 1884 estarecord -c 1 -f S16_LE -r 8000 -t raw
. Aucune idée de ce que c'est ou pourquoi ça fonctionne. -
Quand j'essaie de tuer
arecord
(en tant que root), il se réinitialise et se réinscrit sur le matériel.
Je suis dans une situation très ennuyeuse où je ne sais pas ce qui se passe et je ne sais pas comment le découvrir. Je suis ouvert à toutes les suggestions pour que cela fonctionne à nouveau. Envoyez vos suggestions.
Et voici ce que j'obtiens quand j'arrête le chargement automatique de PA, que je le tue et que je le démarre avec -vvvv
.
