I am facing sound not working issue in few of my newly installed ubuntu systems. Steps taken to resolve this error as below.
- sudo alsa force-reload , then rebooted system but it didn't worked. then reinstalled
2.sudo apt-get remove --purge alsa-base pulseaudio
- sudo apt-get install alsa-base pulseaudio
t. sudo alsa force-reload
After above steps sound worked , It meanse now I am able to here system default sounds , when system restarts I am able to here sound.
But when I am trying to play any video file or music file sound doesn't come.
Now I have installed "Ubuntu restricted Extras"from ubuntu software center. It got installed fine . Rebooted the system but still it didn't worked.
So friends please guide me how to resolve this error. Here sound driver is working fine, as I am able to here system default sounds.
