** Description changed:
I noticed when i restarted my laptop (HP 630 after installing the latest
stable linux kernel (linux-image-13.110.13-generic:amd64
13.11.0-13.20), there was no sound, i could not connect to the internet
via either cable or wireless and the graphics was slow. On further
inspection i found out no network manager displayed network devices
available and there was a dummy output in sound settings.
After searching the internet i came across this link ---
http://askubuntu.com/questions/294016/no-sound-in-ubuntu-13-04-only-dummy-output-device-listed
After following the instruction and choosing an earlier version of kernel
(3.11.0-12-generic), all the issues were resolved. I have ubuntu 13.10
installed.
Below is the comment that helped. Hope this is helpful in some way to deal
with the issue with the latest kernel.
I also had it - Does sound work before reboot after one update? If yes it is
probably the same.
It's bug related to kernel 3.8.0-18.
Run uname -r to check your version of Kernel. If it is 3.8.0-18-generic - try
next steps
Reboot and in GRUB select Advanced options
Chose Ubuntu with Kernel ... (Any before -18)
Also you can subscribe this bug at Launchpad, I hope they will fix it soon
