utilisation de microphone pour enregistrer sa voix

Dommage, le microphone associé à la webcam sur mon portable ne semble pas reconnu :/ (ah bin si en fait ça a l'air de fonctionner avec qaRecord... comme quoi avoir plusieurs outils dont un avec une représentation graphique permet de voir le niveau sonore).
Je n'ai pas de micro, donc pas de possibilité de le brancher sur la prise jack à l'avant du clavier (de toute façon la prise pour des écouteurs ne marche déjà pas, donc j'ai des doutes).

Heureusement, il me reste une logitech QuickCam Pro 4000 qui a un micro intégré et qui est reconnu, au branchement il apparaît dans /var/log/messages :
usbcore: registered new driver snd-usb-audio

et il est listé par les différents outils, cf. ci-dessous

Bon finalement, trop difficile de sélectionner le micro de la webcam en utilisant la conf' ALSA (sans doute pas super bien supportée par les différents logiciels...), donc comme le micro intégré au portable a l'air de fonctionner correctement, c'est ce que j'utilise. Il me faudrait des écouteurs audios qui fonctionnent, mais bon (pour éviter l'effet larsen par exemple).

outils pour l'enregistrement

Bon, ce qui est bizarre c'est que autant gnome-alsamixer voit bien qu'il y a un périphérique usb permettant d'enregistrer, gnome-sound-recorder n'a pas l'air de savoir le sélectionner :/ donc j'ai regardé avec d'autres outils :
