problemi audio dopo installazione aggiornamenti

[lauu]

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.

[lauu]

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

Prossimo test: crea un utente nuovo, da "gestione utenti" o con

Codice: Seleziona tutto

sudo adduser NOME

e verifica con quello.

[lauu]

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

Codice: Seleziona tutto

alsamixer

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:

Codice: Seleziona tutto

sudo apt-get install build-essential gettext ncurses-dev linux-headers-`uname -r` xmlto
tar xvpjf alsa-driver*
cd alsa-driver*
./configure --with-cards=hda-intel
make
sudo make install
cd
tar xvpjf alsa-lib*
cd alsa-lib*
./configure --with-cards=hda-intel
make
sudo make install
cd
sudo ln -s /usr/lib/libpanelw.so.5 /usr/lib/libpanelw.so
sudo ln -s libformw.so.5 /usr/lib/libformw.so 
sudo ln -s libmenuw.so.5 /usr/lib/libmenuw.so 
sudo ln -s libncursesw.so.5 /lib/libncursesw.so
tar xvpjf  alsa-utils*
cd alsa-utils*
./configure --with-cards=hda-intel
make
sudo make install
sudo alsaconf

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 

[steff]

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.

[lauu]

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:~$
::) :-\

[steff]

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

[lauu]

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

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

Now ALSA is ready to use.
 For adjustment of volumes, use your favorite mixer.

 Have a lot of fun!

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..

[gativa]

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

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

[lauu]

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...

[steff]

Hai installato tutti e tre vero?
