Two days ago my audio was fine, today I turned on the machine and it had no sound and in the audio configuration said exit for clumsy
now uninstall and install pulse-audio and alsa-audio but I still have no sound.
Someone who can guide me where the audio problem is?
Try these commands:
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-'uname -r' libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-'uname -r' libasound2; killall pulseaudio; rm -r ~/.config/pulse*; rm -r ~/.pulse*; sudo usermod -aG 'cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'' 'whoami'
Restart and this should be solved; at least in theory, because it did not work for me in the first instance.
What I did next was to install the latest version of the ubuntu 16.04 kernel (I think this is optional, I did it more than anything in case something got corrupted or corrupted with everything I tried). I used the following command:
sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04
It's from the official wiki from ubuntu.
Then I followed the steps detailed in this answer from askubuntu , that I translate, first execute these commands:
pulseaudio -k && sudo alsa force-reload
Then:
pacmd list-cards
If this shows you the available audio cards that would be all, but verify that the system finds them with the following command:
lspci -nnk | grep -A2 Audio
If this returns results and you see the audio cards listed, perform the following steps:
Buala !!! the audio already works !!!
Anything you comment and I answer you, because before doing this I first had to repair alsa since the audio system did not show any sound card, not even "Exit for clumsy".
In case anyone happens to him I recommend you to follow this post and then, when you arrive at the part that says "repair press" follow the steps that I detail here.
I hope it helps you.
Greetings.
