son qui marche pas/plus VIA 8237

blz · 21 sept. 2006

salut, problème de son encore, désolé...
J'avais installé FC5 il y a une semaine sur l'ordi d'un ami avec un dualboot avec le système à fenêtres. Le son sous FC5 avait marché du premier coup; mais suite à un gros plantage du système à fenêtre, j'ai du le re installer, et dans l'incapacité de restaurer le boot loader, j'aidu re installer la FC5... et là, plus de son !
# system-config-soundcard
reconnait bien une carte son : la VIA 8237, maissort pas de son. Ci dessous le fichier scsound.log.

J'ai un peu cherché dans le forum avant de poster... j'ai modifié ainsi le /etc/modprobe.conf, commej'ai trouvé indiqué sur le forum, mais sans succès :

alias eth0 via-rhine
alias scsi_hostadapter sata_via
alias snd-card-0 snd-via82xx
#options snd-card-0 index=0
#options snd-via82xx index=0
#remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx

Le jack est bienbranché et tous les volumes de kmix à fond...

J'ai aussi viré la ligne :
#SWCONF
du fichier /etc/asound.conf , comme trouvé sur un fil, mais toujours sans succès.
Un peu chiant que ça ait marché une fois, et pluis là plus du tout (jeviensde faire 2 ré installes...)

Voilà, sivousavez des pistes, je suis preneur 😉

Ci dessous, le fichier /root/scsound.log après un premier test de system-config-soundcard sans avoir modifier les fichiers cités plus haut :

areuh,
J'avoue que le multimédia, c'est pas mon fort, et bien que des bonnes volontées aient essayé de m'expliquer le fonctionnement de toutes les couches qui se superposent avec linux, je n'ai toujours pas bien compris, mais je dois y mettre de la mauvaise volonté.

Donc pour être sur que la carte son (intégrée) n'était pas cramée, j'ai installé le driver sur le système à fenêtres -> du son, ok. De là, je re installe FC5 pour la troisième fois et là, miracle (bof), dès le premier reboot après l'install, au test de la carte son, le son qui marche -> ? ! ? ! ? !

J'ai pas que ça à faire, mais j'aime bien comprendre. Pourquoi le son ne marche pas avant d'avoir installé le driver sur doze et pourquoi il marche après avoir installé ce driver ? ? ? Ca me laisse perplexe.

Pour essayer de comprendre rapidement, j'ai lancé # system-config-soundcard , testé le son, et bien qu'il y avait du son, j'ai répondu que je n'avais rien entendu pour qu'il crache le fichier /root/scsound.log et le comparer avec le précédent, quand ça marchait pas.

Je n'ai pas fait un diff exhaustif, mais vite vu, je vois que le fichier /etc/asound.conf n'existe pas alors que quand ça marchait pas, il existait.

Voilà, si ça peut dépanner quelqu'un, tant mieux, sinon, désolé pour le bruit.
Ci-dessous, le fichier /root/scsound.log généré par # system-config-soundcard pour un son qui marche.
Merci à tous, @+ 😉

areuh areuh,
décidément, c'est vraiment tordu !
Hier, le son marchait bien après une fresh install de FC5. J'ai fait un "yum update" et ce matin, plus de son !!!
J'ai vu que le fichier /etc/asound.conf était reapparu. Je l'ai viré, toujours rien.
J'ai commenté 3 lignes de /etc/modprobe.conf comme ceci :

[root@localhost ~]# more /etc/modprobe.conf
alias eth0 via-rhine
alias scsi_hostadapter sata_via
alias snd-card-0 snd-via82xx
#options snd-card-0 index=0
#options snd-via82xx index=0
#remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/
modprobe -r --ignore-remove snd-via82xx
[root@localhost ~]#

et après un reboot, le son remarche !

Comprenne qui pourra

blz, le fichier asound c' est pour configurer Dmix, qui est un mixer logiciel, addon de Alsa pour les cartes sons de merde qui ne possède pas de mixer hardware.
bon c est vrai que ça à l' air tordu le truc de L*** mais bon, y en a comme ça qui ont "pas de chance" (cette semaine, une install chez un "deux bras gauches"... du tonnerre...bref...)
Donc le fichier asound n' est pas vraiment obligatoire, c' est juste très fortement conseillé. Le "son" marchera avec ou sans, sns problèmes. C' est juste un "mixeur" alsa (bien meilleur que les bouses comme esd / arts / gstreamer / pulseaudio / phonon )
le modprobe.conf ne fait référence qu' à une carte son : c' est sûr, ça ? tout est là ? (parceque cela semble assez courant sur fed d' avoir un problème dans l' ordre de chargement des modules si 2 cartes sons)
voici peut être une piste à suivre :

alias sound-slot-0 snd-via82xx
remove snd-via82xx /sbin/modprobe -r snd-pcm-oss; /sbin/modprobe --first-time -r --ignore-remove snd-via82xx
install snd-via82xx /sbin/modprobe --first-time --ignore-install snd-via82xx && { /sbin/modprobe snd-pcm-oss; /bin/true; }

Tout n' est pas obligatoire, bien sûr. Et tu doit pouvoir encore en ajouter pour faire encore plus propre sur la couche aoss. (mais bon, le full alsa c est plusss mieux 😉 )

bon au fait on cause de ça, mais j' imagine que tu as bien vérifier que c' était pas simplement la bouse de arts qui posait soucis ?

un peu hors sujet : un kernel rt est prêt au fait (en fait plusieurs le dernier étant un 2.6.19-rt6) pas seulement un vanilla + rt mais vanilla + 324 patches + patch rt modifié... donc full support hardware... Avec ça pour le bruler un peu :

#include <sys/io.h>
#include <stdio.h>
#include <sched.h>
#include <sys/types.h>
#include <unistd.h>
#include <errno.h>
#include <stdlib.h>
#include <time.h>
#include <sys/time.h>
#include <asm/unistd.h>
 
void set_rt(int p) {
        struct sched_param prio;
        prio.sched_priority = p;
        if(sched_setscheduler(getpid(),SCHED_FIFO,&prio) < 0 ) {
                perror("Could not set realtime priority");
        }
}
 
int main(void) {
        struct timespec plop;
        int j;
        syscall(__NR_clock_getres, CLOCK_MONOTONIC, &plop);
        printf("Clock resolution: %d nanoseconds\n",plop.tv_nsec);
        set_rt(99);
#define SAMPN 10000
        for(j = 0; j < SAMPN; j++) {
                struct timespec pl;
                int t;
                pl.tv_nsec = 1000;
                pl.tv_sec = 0;
                syscall(__NR_clock_nanosleep,CLOCK_REALTIME,0,&pl,NULL);
        }
        return 0;
}

Les fous tapent du 9 nanosecondes .... 😉
-> tu sais ce qu' il reste à dire à L*** ?
