Sound not working in Ubuntu 14.04LTS after upgrading from 13.10

I have upgraded to Ubuntu 14.04LTS from 13.10. Before upgrade sound was working fine, but after that its not working. I tried solving this issue from a reference link

Sound not working in Ubuntu 14.04

but still my problem is not resolved.

Solution 1:

Could you apply this procedure let us know if you see any error message. Pulseaudio Log

Don't paste your log file in this site but use this one Paste Bin and share the link.

Sometimes uninstall pulseaudio and resintall it solve the problem

sudo apt-get remove –purge pulseaudio gstreamer* esound*

I put Esound package for be sure unisntalled because it's obsolete and occur bug (never mind). Following a reboot apply:

sudo apt-get install pulseaudio

Add you login in the audio group:

 sudo adduser $USER audio

then reboot

May help.
