[openmamba-devel-it] problema con l'audio SAA7131

[gil]

ciao
avrei un problema con l'audio della scheda dvb... ho provato in vari 
modi ... seguendo le istruzioni in vari post/guide qua e la ... ma non 
ne sono venuto a capo...
i/l driver dovrebbero essere (se non ho capito male... :( )
saa7134_alsa 
ho trovato in un post che potrebbe servire saa7134_oss pero non é 
presente almeno quando tento di caricarlo con modprobe mi torna che non 
esiste....
grazie
