Speakers not working on Ubuntu 12.04 LTS

Asked by Rahul

I have a Dell Inspiron Laptop that had its speakers working till 2 days ago. Now the sound output comes only via Headphones and no speakers.

The following is the output of the command.

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Please run these Terminal commands:

sudo apt-get update

sudo apt-get install linux-headers-3.13.0-85-generic

sudo apt-get install linux-image-3.13.0-85-generic

sudo apt-get install linux-image-extra-3.13.0-85-generic

Then reboot into GNU/Linux kernel version 3.13.0-85-generic and retest sound output.

Please also check that all mixer channels are set to 100% volume and unmuted in alsamixer.
