Actuellement je me plais à tester quelques jeux sur ma toute fraîche et encore instable Fedora 7 (version stable prévu le 31/05). En testant FlightGear, le simulateur de vol Open Source, je me suis heurté à un petit problème de carte son dès le lancement :

llaumgui@enterprise ~> fgfs

Après quelques minutes de recherche sur mon ami Google, j’ai enfin trouvé la solution sur leWiki de FlightGear, dans mon cas :

llaumgui@enterprise ~> cat .openalrc
(define devices '(alsa))
(define alsa-out-device "plug:dmix")

Tout ça pour me rendre compte que je n’aime pas les simulations de vol ;-)… M’aura quand même donné l’occasion d’un petit billet…
