Risolto [Audio] Pc muto dopo aver avviato skype

[ilprofugo]

Salve a tutti, sono giorni che giro per il forum cercando una soluzione per il mio pc ma non sono riuscito a capire perché non mi si sente l'audio. Di seguito vi ho scritto tutte le informazioni in mio possesso riguardante il mio sistema, il kernel è 2.6.24-19-g, la versione di ubuntu è la Ubuntu 8.04, Hardy Heron. Il sistema audio prima funzionava perfettamente poi un mio amico ha smanettato cambiando qualcosa per far sentire skype e da allora non mi si sente più niente.

Grazie
Fabrizio

prova a vedere nel file /etc/asound.conf

magari le modifiche le ha apportate li...

[ilprofugo]

Anche questo file avevo trovato su qualche forum di modificarlo, attualmente questo è il suo output

mmm quelle righe mi sembra che servino per migliorare il suono in gnome...ma a quanto ricordo dovrebbero essere obsolete... mmm magari prova a vedere nel forum di skype cercando la tua scheda audio...

[ilprofugo]

ok risolto

semplicemente basta

sudo /etc/init.d/alsa-utils reset

[tyrchyus]

Ottimo! Scrivi risolto nel primo post e sei a bolla!!!
