    Unhappy Audio stopped working after performing upgrade in ubuntu 12.04

    I have dell inspiron 15 3542 series laptop with ubuntu 12.04 as operating system.
    Yesterday I had executed following commands from terminal
    sudo apt-get update
    sudo apt-get upgrade
    The above mentioned processes were successfully executed but when I did reboot ,there was no sound from inbuilt speakers on laptop.
    After that I tried executing above commands and did reboot multiple times but the issue still persists.
    Also I am receiving following notification in Google chrome browser
    This computer will soon stop receiving Google Chrome updates because this Linux system will no longer be supported.
    Looking forward for appropriate solution ASAP

    This may sound silly, but did you try increasing the volume?

    It tends to default to zero.

    Try aumix or amixer and crank it up.

    Maybe the sound was somehow muted? Try setting it with pulse audio volume controller and/or alsamixer (use arrow keys to select and adjust, m to (un)mute, escape to exit). In terminal:
    Code:
    pavucontrol
    alsamixer
    They should be integrated, but I have seen cases where this didn't work correctly. Also, I'm a but rusty on 12.04. It's a long time since I used it.

    As for your chrome issue: it seems that google will drop support for 12.04. Your options are to switch to a different browser or move to a later version of Ubuntu. You can switch to 14.04 (upgrade or clean install) or, if you can wait a few weeks, directly to 16.04 (clean install).

    Right click on the sound icon at the top of your screen to see if the correct sound device is high lighted
