Audio output and input stopped working after the last update
- by renatov
I'm using Ubuntu 14.04 and everything was perfect until todays's update. Now my audio output (speakers) and input (microphone) stopped working. I guess it's a driver issue, but I need help to debug this problem and to solve it. I have a Dell Inspiron 5421 notebook with an Intel audio integrated sound card:
$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
If I go to Ubuntu Settings Sound Output, it doesn't show my Intel card there anymore:
The same for the Input tab, it doesn's show my Intel card there anymore:
Could you please help me?
