I tried solving from below reference link.

And i have attached logs for pulseaudio to the below reference link.


but after this sound icon always showing mute which was showing near battery icon, but when checked from system settings->sound->output volume its showing unmuted. I tried changing from mute to unmute from icon near battery icon but its not changing. And after playing videos its showing "An error occurred Could not initialize supporting library" error message is coming. Please suggest how to resolve this issue.

I have solved my problem for headset but still speakers are not working. I have taken the reference from the mentioned link.....Sound not working in Ubuntu 14.04LTS after upgrading from 13.10


Actually, typing in the command sudo apt-get install pulseaudio helps me watch different videos on Videos. Just remember to not remove PulseAudio, or you might get this message that I got in Videos:

Could not initialize supporting library.

It's because I don't have PulseAudio installed. Thank you!
