Ubuntu 18.04 no audio error

                                                     UBUNTU 18.04 NO AUDIO ERROR


    I am posting the fix which worked for me on Ubuntu 18.04.


Permanent fix:

  1. sudo apt install alsa-tools-gui
  2. Run hdajackretask
  3. Parser hints > jack_detect = no
  4. Apply now
  5. Install boot override

Some times you get error while on Apply now like,

/sys/class/soynd/hwC0D2/reconfig: device busy

then kill the process like 
$ sudo pkill pulseaudio

Now reboot.

To get your directory name just login to Azure active directory and switch to users and select the user for whom the access is needed. The user name has a mail ID like thuvaragesh@ example.com here example.com is your directory name.
