and run these commands as well 

sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload

rebooted the system also updated the kernel using this link

uname -r

gives 4.15.0-99-generic

sudo apt-get update
sudo apt-get dist-upgrade

kernel version remains the same after that (4.15.0-99-generic )

the command pulseaudio --start gives 

 N: [pulseaudio] main.c: User-configured server at {d31e5be658484174a49d9c408bcecf46}unix:/run/user/1000/pulse/native, which appears to be local. Probing deeper.

sudo apt-get install pavucontrol
pavucontrol

and its configurations is set to 

analog stereo duplex

and switched to 

Analog stereo output
