The sounds stops immediately if I unplug the laptop charger and nothing will make it produce sound again even with my own sound devices connected to the laptop! I'm using Ubuntu 12.04 LTS on a G570 Lenovo.

Maybe it's a drivers' problem, so be sure of install them. If you didn't install any drivers/your soundcard's drivers yet, you can follow the next steps:

  • Click on the Dash
  • Search for Additional and click Additional Drivers
  • Wait a bit, and you'll see a list with all the compatible drivers for your computer. You can install your graphics card drivers (I usually install the post-release drivers) and all your other devices.
  • Check if your soundcard name appears at that list, select the entry for it and click Activate. After a while, you'll have to restart your computer.

After restarting, it should be working OK if it was a driver-related problem. I hope it works to you and tell us soon!
