[Fedora 8] pulseaudio
Résolu
Bonjour,
bien que je n'ai pas de problème particulier avec le son, je m'interrogeais sur ces messages d'erreurs :
[root@localhost redfox]# cat /var/log/messages | grep pulseaudio

Au passage, verifie que le user est bien dans les groupes "pulse-rt" et "PolicyKit"
donc rien de bien méchant bien que je n'ai pas tout compris sur pulseaudio mais apparemment pulseaudio c'est pas "tip-top" !
une batterie de commandes intéressantes :

[redfox@mandriva ~]$ ps aux | grep pulse
redfox 24438 0.0 0.0 3140 800 pts/1 S+ 19:31 0:00 grep --color pulse
[redfox@mandriva ~]$
[redfox@mandriva ~]$ cat /etc/pulse/daemon.conf
; default-sample-rate = 44100
je modifie donc cette ligne par :
default-sample-rate = 44800
cela devrait régler les messages du type : "Device surround51:0 doesn't support 44100 Hz, changed to 48000 Hz."

Bonjour,
Sous Fedora, l'accès aux périphériques locaux (scanner, imprimante, son, etc.) est accordé dynamiquement à l'utilisateur qui se connecte en local. Ceux qui se connectent à distance (par exemple par ssh) ne le peuvent pas.
Ceci est fait par attribution d'une ACL sur les entrées /dev lorsque l'utilisateur s'authentifie en local.
Par exemple si l'on fait : ls -l /dev/snd/seq on obtient :
crw-rw----+ 1 root root 116, 3 2008-08-24 08:11 /dev/snd/seq
Le signe + à la fin des permissions montre qu'il y a une ACL, que l'on peut voir par getfacl /dev/snd/seq :
# file: dev/snd/seq
# owner: root
# group: root
user::rw-
user:manu:rw-
group::rw-
mask::rw-
other::---
On y voit que l'utilisateur manu a obtenu un droit en rw
Sous gnome (je ne sais pas pour KDE) ces droits accordés à la connexion locale sont gérés à travers le menu >System>Preferences>System>Authorizations
Les périphériques standard (imprimante, etc) y sont bien déclarés par défaut, mais il semble qu'il y ait quelques ratés pour les périphériques inhabituels.
Dans le cas de pulseaudio, il serait bon d'y jeter un oeil

bonjour,
merci pour les explications !
tout d'abord, je n'ai pas de souci de son ! cela fonctionne très bien ! c'est juste pour essayer de comprendre !
Sous gnome (je ne sais pas pour KDE) ces droits accordés à la connexion locale sont gérés à travers le menu >System>Preferences>System>Authorizations
Les périphériques standard (imprimante, etc) y sont bien déclarés par défaut, mais il semble qu'il y ait quelques ratés pour les périphériques inhabituels.
j'étais tombé dessus par je ne sais quelle commande, j'avais survolé et observé la même chose.
<EDIT : commande polkit-gnome-authorization EDIT>
je me colle deux commandes très intéressantes :
mplayer -ao pulse /usr/share/sounds/phone.wav mplayer -ao alsa /usr/share/sounds/phone.wav
source : https://lists.autistici.org/message/20080811.090134.bc2e0643.en.html
en résumé j'ai observé pas mal de problèmes récents (2008) avec pulseaudio quelle que soit la distribution linux. de là à dire que pulseaudio n'est pas encore très au point, il n'y a qu'un pas !

j'ai donné l'authorisation à mon user pour le périph son ! je n'ai malheureusement pas vu de différence après redémarrage de la machine !
de toute façon j'arrete là car pour moi le son fonctionne (Rythmbox, mplayer, animation flash via firefox, ...
...et en plus je ne voudrais pas "planter" le son à force de "bidouillages" ! :-) -
ce qui est vraiment drôle c'est que sur la mandriva, j'ai également pulseaudio et pourtant voici les seuls messages d'erreur que j'ai :
[root@mandriva log]# cat messages | grep pulse
Aug 24 20:22:48 mandriva pulseaudio[9723]: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Opération non permise
Aug 24 20:22:48 mandriva pulseaudio[9723]: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Opération non permise
..comparé à la flopée de messages d'erreur sur la fedora. peut-être comparer les différences !
à noter que sur la mandriva je suis sous KDE ! -
avec Fedora 9 :
module.c: Failed to load module "module-x11-xsmp" (argument: ""): initialization failed.
