Let me explain the problem, since this morningI have no more sound on my debian.
The only audio output I can find is the "dummy output".
When I try ask to aplay -l to display my sound cards, here's the output
Code: Select all
device_list:268: aucune carte son n'a été trouvée...
But I can still see my card(s) using lspci :
Code: Select all
