Super, merci... avec une version plus ancienne, on est en 3:17:0, ça avance.
Je te file le lien vers les firmware 1.6: https://mega.nz/file/BllQRSTI#dVLGUyaLIrMymdabz-zswK9P2_Qv3k-RphHHiXOC6OY

Malheureusement meme résultat, mais avec un toujours un décalage de 1 version entre le kernel et le firmware ... ???

@davidb2111

Alors ... je suis reparti d'une fresh install 7.2.1b3 sur clé USB car je me suis emmêlé les pinceaux sur les "rm" entre les differentes versions ... quitte à tester à une différence, autant le refaire propre

Du coup j'ai maintenant le retour dans les "OPTIONS DU SON" le retour de la ligne "SORTIE AUDIO" (elle avait disparue jusqu'à maintenant).
J'ai le choix entre ANALOG et MULTICHANNEL OUPUT, par contre toujours pas de son.

Le driver à l'air bon maintenant ... YES !!!

alsa_card.pci-0000_00_1f.3-platform-sof-nocodec

Essayons avec

pacmd set-card-profile 'alsa_card.pci-0000_00_1f.3-platform-sof-nocodec' 'output:multichannel-output'

leced

@davidb2111 reboot à chaque test ?

test : redémarrage emulationstation : KO, reboot : KO ... aucun changement

plus besoin de rebooter, maintenant faut réussier à router le son vers la bonne sortie.
Tu utilises les HPs intégrés du portable?

leced

@davidb2111 non, normalement c'est la sortie HDMI, je viens de tester avec un casque branchée (sortie casque) ... pas de son (j'ai testé analog et multichannel)

@leced

Ok, tu pourrais me refiler les logs de boot, stp? Y a peut-être encore autre chose qui manque

@leced cette ligne intéressante ?

May  4 20:18:48 RECALBOX user.info kernel: [    0.129077] ACPI: Added _OSI(Linux-Lenovo-NV-HDMI-Audio)

davidb2111

@leced

on va essayer de passer un paramètre au kernel:

mount -o remount,rw /boot
sed -i -E 's/^(\s*linux.*)/\1 snd_hda_intel.dmic_detect=0/' /boot/grub/grub.cfg
sed -i -E 's/^(\s*linux.*)/\1 snd_hda_intel.dmic_detect=0/' /boot/EFI/BOOT/grub.cfg

et ensuite reboot

je n'ai qu'un mot à dire : BRAVO !!!!

1000x mercis d'avoir pris le temps de déb****r mon petit PC de récup, ça m'aurait fait mal au coeur de rester figé à la 7.1.1

davidb2111

@leced

Ouf! Chapeau et merci aussi!
Pourrais-tu m'envoyer les logs une dernière fois?

Normalement, ça sera inclus pour la 7.2.2

leced

@davidb2111
pour info, je n'ai plus ANALOG et MULTICHANNEL mais ... un choix beaucoup plus lisible, ici

Petites remarques (mais pour le coup vraiment pas important) :

J'ai pas de son au reboot (boot video ... sans son), et lag de la vidéo (= effet remarqué suite à la perte de son à la bascule 7.2), rien n'a changé à ce niveau
Lorsque je choisis HDMI / DISPLAYPORT, au reboot c'est le SPEAKER qui prend le relais, meme si l'information HDMI / DISPLAYPORT est sélectionné, je dois le re-sélectionner la meme valeur (ex: HDMI / DISPLAYPORT), ça freeze 1 sec, et le son repart sur la télé. bizarre. Peut-etre est-ce du à nos x manipulations ?

Ci-joint le log de boot : ici

c'est un bug connu, on n'a pas de contournement pour l'instant. J'espère trouvé un correctif pour la prochaine version

Étrange. Tu peux forcer une reinstall d'usine. Ça va supprimer les fichiers qu'on a inclus dans /lib, mais pas la conf qu'on a modifiée en dernier et qui solutionne ton problème.
