Audio multicanale AC3 & C.

[HexDEF6]

Allora il mio problema e' semplice semplice:
su un paio di computer ho schede sonore multicanale (una sb live value e una fortissimo 3)
entrambe fanno suonare tutte le casse attaccate.....ma dove sono finiti gli effetti dolby digital (o come diavolo si chiamano) dei dvd o dei divx (fatti da me con audio ac3) ???
Tanto per fare un esempio: nel tredicesimo guerriero c'e' una scena dove (sotto win) si sentono le mosche che ti girano attorno.... sotto linux no.. il sonoro e' in stereo ma le casse dietro sono la scopiazzatura di quelle anteriori... questo sia con xine (in teoria l'audio e' impostato per il 5+1) sia con mplayer (lanciato con l'opzione -channels=6)....
ovviamente entrambe le schede girano con driver alsa, su mdk 9 e 9.1.

Qualche soluzione/consiglio???

Ciao

[Kernel Panic!!]

-channels 6 -ao alsa9:surround51

coi driver oss basta -channels 6, non chiedermi perchè...

[HexDEF6]

Grazie provero'.... adesso devo scappare... comunque entro questa sera ti dico se funziona!!!!

Ciao

[HexDEF6]

niente da fare
mplayer mi dice che non puo aprire il device e setta no sound
eppure gli alsa funzionano visto che xmms con il plugin per l'output alsa funziona benissimo....
Se invece uso mplayer -channels 6 (senza -ao alsa9...) si sentono solamente i rumori di sottofondo del film (credo quelli che dovrebbero essere indirizzati alle sole casse posteriori) e niente canale centrale

Se puo essere utile posto tutto quello che mi spara fuori mplayer....

Grazie!

P.S. qui posso fare prove solo con la fortissimo 3 e non con la live

[Kernel Panic!!]

usi per caso arts (il server sonoro di kde) o esd (quello di gnome)? in tal caso disabilitali... (parlo di arts, mai provato con esd) fan altro che casino

[HexDEF6]

Niente da fare...
anche disabilitando esd il risultato non cambia

Altri suggerimenti?

[AnonimoVeneziano]

Il film che stavi aprendo è fight club?

Comunque mi spiace, non so come aiutarti perchè ho solo un 2.1
Ciao

[VICIUS]

aggiungi l'opzione -v per avere un log piu dettagliato da mplayer e ripostalo.
che versione di alsa usi ??

Sono d'accordo.
Ma se settato bene funziona pure con Arts

Innanzitutto vedi se mplayer riconosce bene gli alsa.

mplayer -ao help
Ti dara' una lista di driver supportati quando hai compilato mplayer.
Se trovi alsa9 è tutto oK e possiamo andare avanti.

Se hai un decodificatore Dolby Digital esterno (anche uno piccolo come quello delle Creative DTT2500 o simili)
devi forzare il segnale sull' SP/DIF lasciando uscire il segnale grezzo (non codificato ) dalla tua Live.
Altrimenti verrebbe codificato 2 volte con scarsa qualità.

In questo caso avvia mplayer da riga provando con questi parametri...

mplayer -dvd 1 -ao alsa9 -ac hwac3

Se non hai decodificatori esterni e ti appoggi sulla codifica della Live
scrivi

mplayer -dvd 1 -ao alsa9 -ac a52

Se così non risolvi dimmi che mixer usi che lo risolviamo definitivamente

Il problema e' che mplayer non l'ho compilato io ma e' quello del plf.....
Gli alsa sono i 0.9rc2 della mandrake 9.0
la scheda audio e' una fortissimo 3 con attaccato il sistema 5.1 della hercules (analogico)


adesso riposto il log con l'opzione -v

Ma sei sicuro di aver settato bene alsa? Dice di non trovare Schede audio.

Il che è strano dato che hai detto che alsa funziona con li altri programmi.... come hai settato le impostazioni in /etc/modules.conf ? anzi, postacelo, così facciamo prima

facendo prove con alsamixergui noto che sembra tutto funzionare perfettamente: posso alzare indipendentemente il volume delle casse anteriori di quelle posteriori del canale centrale e del sub... non ho provato gli altri 2 canali (la fortissimo 3 e' una 7.1) perche' non ho attaccato altre casse, ma ci sono i volumi anche per quelle... se puo essere utile posto il nome di tutti i canali cosi come appaiono nell'alsamixer....

comunque sul sito dell'alsa dice che tutte le schede con il mio chippino cs46xx supportano il multicanale...

Al 98% risolvi ricompilando sia gli alsa che mplayer.

Ti avevo detto di fare un comandino
Anzi postaci l'output di questi due comandi

mplayer -ao help
mplayer -ac help

Così vediamo se mplayer quando fu compilato aveva abilitati gli AC3 decode e gli alsa9.

E' importante l'output di questi due comandi. Altrimenti perchè continuare a parlare se non sappiamo che supporti hai
