Ubuntu 12.04 sound problems "Dummy output" and how to fix it.

0 Comentarii
Lately I've noticed many Ubuntu users having troubles with their sound. Basically there is no sound output either to the speakers or headphones, and the sound properties output reports a "dummy output". So what should we do now? I've discovered that this bug is related to alsa daily update, so basically if you've done this into the terminal: 
"sudo add-apt-repository ppa:ubuntu-audio-dev/alsa-daily
sudo apt-get update
sudo apt-get install alsa-hda-dkms"   all you need to do is remove alsa-hda-dkms. You may remove it either by searching it in Ubuntu Software Center of typing into the terminal:  apt-get purge alsa-dha-dkms

Good luck!
