I finally decided to write to you because after a lot of researches on the web I didn't find a working solution.
Today, after an update, it is no more possible to hear any sound.
I removed and re-installed alsa and pulseaudio
I did
Code: Select all
sudo alsa-force reload
Code: Select all
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
I tried this way
Code: Select all
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
I read on a forum to check this file
Code: Select all
cat /proc/asound/card0/codec* | grep Codec*
cat: '/proc/asound/card0/codec*': No such file or directory
Any idea on this issue?
Thank you in advance, I am pretty desperated
