Je viens d'acquérir un xps 13 9340 et j'ai le même soucis que viewtopic.php?t=23095 : pas de webcam ni de son.
Je ne voulais pas déterrer le sujet donc me voici me voici en train de faire un sujet pour résoudre mon soucis de son...
pour commencer j'ai une install qui utilise pipewire (j'ai utilisé archinstall). j'ai installé sof-firmware ainsi que alsa-firmware (même si je ne pense pâs que cela ait changé quoi que ce soit).
J'ai tenté de faire la manipulation décrite ici, sans succés je n'ai toujours qu'un "dummy output".
Pourriez-vous m'aider ?
quelques commande en vrac :
