Da un paio di mesi uso Ubuntu 10.04 Lucid Lynx, e mi sono trovato veramente bene ... almeno finchè non ho tentato di fare in modo che il sistema permettesse di riprodurre contemporaneamente 2 flussi audio (Rythmbox e Flash, nel mio caso)
Ho trovato decine di guide una più dettagliata dell'altra, ma nessuna ha prodotto il risultato sperato. Anzi una ha fatto in modo che il sistema non riconoscesse più la scheda audio.
Sempre cercando su Google ho trovato questa guida

Qui hanno inserito una soluzione per un problema identico al mio.
La soluzione in questione è la seguente:
Non l'avrei attuata se non avessi letto che un utente l'ha testata con successi sul 10.04.Originally Posted by TacheDeChoco View Post
After so many many attempts to solve my audio problems when upgrading to Karmic, I finally found a working solution !
First, let me decribe what the problem was:
1) no audio card was detected at all
=> cat /proc/asound/cards returned an empty content
=> cat /proc/asound/devices did not include any audio devices
=> 'Hardware' tab in sound preferences was empty
2) the audio tray indicated a "dummy output"
SOLUTION
========
For those who do not have a fresh Karmic install (in other words those who have upgraded their Jaunty install), you should update your Grub BEFORE applying the 2 steps described hereunder:
sudo update-grub
Step1: make the sound card being recognized
=> Purge alsa-base and pulseaudio, eg:
sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload
Now, reboot, you shoud now SEE (but maybe not yet hear) your soundcard.
Give a try to:
cat /proc/asound/cards
and see if any card is listed...
Step2 : If the sound is crapy, you MAY have to edit the alsa config file:
sudo gedit /etc/modprobe.d/alsa-base-conf
a) comment (#) the following line:
# options snd-hda-intel power_save=10 power_save_controller=N
b) Add a new line
options snd-hda-intel probe_mask=1 model=hp
Replace "hp" with appropriate computer model. See here
Good luck !
Bernard.
Comunque il problema è che al punto
