[gcompris-devel] Gcompris, problemi audio

[Eros Rasetto]

Ho un problema con Gcompris, sia su mandrake9.2 che con debian sarge, 
manca completamente la parte audio.
I file audio sono in formato .ogg, se li eseguo con Xmms vengono
riprodotti correttamente, perciò penso che la scheda audio non abbia
problemi. Tale malfunzionamento si verifica anche eseguendo Gcompris dal
cd di Knoppix 3.3.
Qualcuno mi sa dare qualche consiglio? Ci terrei a far funzionare questo
programma, perchè è veramente bello.
Allego l'output di Gcompris lanciato da terminale.
