This ppa contains utilities related to HDA Intel sound cards.
Note: as of Ubuntu 13.10, hda-jack-retask is part of alsa-tools. Just install the alsa-tools-gui package from the regular archive and start "hdajackretask". (Note: if you get this error: "Failed to create file '/home/<user>/.pulse/client.conf'", try symlinking .pulse to .config/pulse - and remove the symlink again when you have closed hda-jack-retask.)
J'ai fait la commande qu'il me demande sauf que ça ne marche pas ^^
