Sound Card – Ubuntu 14.04 Does Not Recognize Sound Card


Good afternoon everyone! I'm going to be objective in my problem.

Before I was using Windows 8 on my notebok and ubuntu on the desktop. I decided to test the update 14.04 in the notebook, installed and worked perfectly, when one day I called and the sound wasn't working anymore, I went to look at the audio configuration and saw that he wasn't recognizing the audio card. Can someone help me?

$ aplay: device_list:268: No sound card found...

$ lspci -v | grep -A7 -i "audio"
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

I had the same problem. You can solve it using the following command:

sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2

Then just restart the computer.
