Debian: Probleme de son sur le PowerMac G5

En lancant MPlayer, le message ci-dessous s’affiche a l’ecran.

Avec VLC,

J’ai commence par ajouter le paquet « pulseaudio » a partir de synaptic (ou encore, en ligne de commande, aptitude install pulseaudio), puis de voir ce que ca va donner.

 En faisant quelques recherches, le probleme de son sur les PowerMacs est apparement un bug qui n’a pas encore ete corrige. Pour ce faire, ajouter les module des noyaux snd-aoa puis de mettre en commentaires le contenu du fichier /etc/modprobe.d/blacklist.local.conf.

root@debian:~# cat /etc/modules
apm_emu
loop
# snd-powermac
snd_aoa_i2sbus
snd_aoa_fabric_layout

# snd_aoa_codec_tas
snd_aoa_codec_onyx

root@debian:~# cat /etc/modprobe.d/blacklist.local.conf
# Local module settings
# Created by the Debian installer

# blacklist snd-aoa-codec-tas
# blacklist snd-aoa-fabric-layout
# blacklist snd-aoa-i2sbus
# blacklist snd-aoa-soundbus
# blacklist snd-aoa

Apres redemarrage de l’ordinateur, j’ai du son mais uniquement en sortie casque. Pour avoir le son au niveau des haut-parleurs internes, il faut verifier que toutes les sorties audio ne sont pas muettes.

Voici quelques informations supplementaires qui pourraient etre utile pour verifier les problemes de son.
