I recently install Ubuntu and i'm dealing with some audio problems. I have no digital sound even thought Digital Output is selected.
Anyway, the command did solve the problem for a while. But now has no effect.
Here is the link i received after executing the following command
wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh
