Help con Mplayer (problemi audio)

[Zeno Cosini]

Ciao ragazzi, non riuscendo a vedere filmati con l'audio con xine ho provato ad installare VLC sulla mia Knoppix. Il problema come ingenuamente speravo non era il player, infatti dopo aver installato anche mplayer riesco al massimo a visualizzare il flusso video senza però avere un output audio, eccovi cosa "dice" mplayer:

MPlayer interrupted by signal 15 in module: sleep_usleep

Che devo fare? Non ho mai avuto problemi relativi all'audio con linux su questo portatile, prima avevo mandrake, quindi non so proprio che pesci prendere, magari si reisce a comprendere il problema da ciò che dice mplayer...
Cmq non è che l'audio nn funzioni proprio, infatti ad esempio i suoni di Gaim vengono riprodotti e provando un mp3 con XMMS veniva riprodotto (anche se a velocità accelerata tipo falsetto)...

Ragazzi nessuno riesce a darmi una mano? Linux dice che ha un problema con /dev/dsp... Io non so proprio cosa fare!
please...

Che driver usi oss ? alsa ?
Hai per caso qualche demone audio che gira quando cerchi di lanciare un filmato ?

Prova a specificare il driver usando -ao nome_del_driver

ciao

[Zeno Cosini]

Intanto ti ringrazio per l'aiuto, se ho ben capito devo scrivere così:
mplayer /home/zeno/Desktop/1.mpg -ao alsa
oppure
mplayer /home/zeno/Desktop/1.mpg -ao oss
in entrambe i casi i risultati sono questi:

mplayer /home/zeno/Desktop/1.mpg -ao alsa

Hai per caso qualche demone audio che gira quando cerchi di lanciare un filmato ?

Onestamente non lo so, se mi dici come si vede te lo dico...
Ti ringrazio e spero con il tuo aiuto di risolvere questo problema...

[Zeno Cosini]

Vicious dove sei finito? (scherzo) Nessuno mi sa aiutare?

[VICIUS]

audio_setup: Can't open audio device /dev/dsp: Dispositivo o risorsa occupata

Questo messaggio dice che la risorsa è gia occupata. Quindi c'è gia qualcosa che usa il dispositivo audio. Proabilmente il demone audio del tuo DE. Se usi kde il demone si chiama artsd. Ne esistono altri ma questo è il piu comune puoi controllare se è avviato tramite top o ps auxb.

Prova a uccidere il processo tramite killall -9 nomeprocesso. Se proprio non riesci a trovare chi tiene occupato /dev/dsp puoi usare fuser /dev/dsp per sapere il pid giusto.

Io uso kde e ho disabilitato artsd all'avvio tramite il pannello di controllo anche perchè di avere i suoni quando le finestre si ingrandiscono non mi interessa.

La cosa che è piu strana è che specificando il driver da linea di comando mplayer viene terminato da un sig11. Un segmentation fault non è una bella cosa forse ci sono gia dei problemi nel pachetto che hai installato.

ciao

[Zeno Cosini]

grazie carissimo! ora sto ripassando che domani ho l'ultimo esame prima delle vacanze, magari dopo provo!

[Zeno Cosini]

In realtà ho scoperto che il processo che teneva occupato /dev/dsp era gaim... una volta killato l'audio finziona... però mi sembra strano...
