Forum Ubuntu-it

Salve, sto usando da pochissimo ubuntu 10.04 e sono veramente alle prime armi, quindi vi prego di essere il più dettagliati possibile nell'aiuto  :P
Ho installato gli ultimi aggiornamenti dal gestore aggiornamenti e dopo aver riavviato, come richiesto, l'audio non mi funziona più. Ho controllato la regolazione del volume su pulse audio, ma tutti i valori sono al massimo. L'icona dell'audio in alto sulla barra è segnata come se fosse stata selezionata l'esclusione dell'audio, cosa che però su pulseaudio non risulta. Inoltre cliccando sull'icona -oltre a "preferenze audio" e la barra di regolazione del volume- viene visualizzata l'opzione "escludi audio", che però non può essere selezionata.
qualcuno sa come posso risolvere? ho letto tantissime discussioni ma nessuna ha risolto il mio problema.
grazie  ;D

Hai provato di avviare con un kernel precedente? Premi shift all'avvio per accedere al menu grub, seleziona la terza o quinta voce.

niente, solito problema anche con gli altri kernel...

Prossimo test: crea un utente nuovo, da "gestione utenti" o con e verifica con quello.

anche con un nuovo utente, stesso problema... ho letto che molti consigliavano di guardare alsamixer, possibile che io non ce l'abbia? lo devo installare?
grazie

Da terminale controlla se hai 00 sotto e non MM, ma credo che è a posto. Se anche il secondo utente non ha audio è escluso una impostazione sballatosi  nella home. Potresti provare di compilare i driver da sorgente, non mi vengono altre idee ( a parte disinstallare alsa e reinstallarlo)

Scarica gli ultimi driver, alsa-lib e alsa-utils da
http://www.alsa-project.org/main/index.php/Main_Page (incima sulla destra),
salvali nella home (non sulla scrivania!) poi un copia-incolla riga per riga nel terminale:

ho avuto un problema: nell'attesa di una risposta, ho seguito questa guida http://it.bongolinux.com/ubuntu-muto-ec ... lsa/37439/, ma al punto cd alsa/lib* il processo non andava avanti, quindi ho deciso di provare a ravviare e vedere cosa succedeva... il computer non riusciva a arrestarsi, quindi ho dovuto staccare la spina. Al riavvio ovviamente non è stato risolto il problema audio. Credi che debba provare comunque i comandi che mi hai dato? oppure meglio disinstallare e reinstallare(nel caso dovresti dirmi come procedere, per favore  :-[)
Se da terminale do il comando alsamixer-come mi avevi chiesto- mi viene scritto: "impossibile aprire il mixer: Nessun file o directory"
grazie mille ancora 

La guida è quasi identico, cd cambia la cartella, se non sei pratico nel terminale usa copia-incolla di ogni singola riga, continua pure o ricomincia da capo.

ho provato, ma già al secondo passaggio mi esce scritto questo:
laura@ubuntu:~$ tar xvpjf alsa-driver*
tar: alsa-driver*: funzione "open" non riuscita: Nessun file o directory
tar: Errore irrimediabile: uscita immediata
tar: Child returned status 2
tar: Uscita con stato di fallimento in base agli errori precedenti
laura@ubuntu:~$
::) :-\

L'hai messi sulla Scrivania, scommetto. Devono essere nella home(accanto scrivania, documenti ecc), le tre cartelle alsa-qualcosa

ok, ho spostato i file, ma mi viengono fuori degli errori  >:(

...grazie

Per favore incolla la prossima volta un affare così tra tag "codice" (bottone # sopra la faccine) 

Assumo che le prima due (driver lib) hai complilato e installato senza errori.

Prova la versione 1.0.23 di alsa-utils, rimuovi la cartella alsa-utils-1-0.24.2 e dai scompattala e riprova

per scompattarla che comandi devo dare?  ???

che devo selezionare?

Presumo il primo, comunque per conferma apri un altro terminale, dai e vedrai quale è il dispositivo audio della tua macchina.

(la prima lettera è una elle e non un 1)

con questo messaggio dovrei quindi aver concluso?
però per esempio se do il comando alsamixer, mi viene ancora scritto che è impossibile aprirlo e che non trova file o directory..

Stando alla guida che hai linkato dovresti riavviare il sistema. Inoltre:

Alsa una volta installato si setta automaticamente con il volume al minimo

uff... ho riavviato, però ancora cercando su terminale alsamixer mi dice che non lo trova, inoltre(non so se c'entra qualcosa) su preferenze audio come dispositivo per l'audio ho output dummy...

Hai installato tutti e tre vero?
