I am struggling with no sound problem on Ubuntu 12.04 and now on 12.10. I went through a lot of forums mentioning this issue and I have tried a lot of different solutions that worked for others but not for me. There is no sound from speakers unless I do
sudo aptitude reinstall alsa-utils
After reboot everything is working fine but after another reboot there is no sound again. So if I wanted to have the audio output on the next boot I have to reinstall
alsa-utils before shutting down the system :)
I have tried to install
alsa-utils not from repository but from the developers site but it did not help, do you have an idea where could be the problem and why the sound works only for the first time the system is on?
If it helps here is output from
