Ubuntu: Dell 11 3000 - Sound for Ubuntu 14.04 LTS. Audio Drivers?


I installed Ubuntu 14.04 LTS on a USB Flash Drive. Booting in Demo Mode seems work Ok in a Dell 11 3000. Microphone input works well, however Audio Output does not. (Tested). I imagine the audio drivers need to be updated.

Appreciate any help.

The configuration of the Dell 11 3000 is:

sudo lshw -class multimedia      *-multimedia                      description: Audio device          product: ValleyView High Definition Audio Controller          vendor: Intel Corporation          physical id: 1b          bus info: pci@0000:00:1b.0          version: 0e          width: 64 bits          clock: 33MHz          capabilities: pm msi bus_master cap_list          configuration: driver=snd_hda_intel latency=0          resources: irq:106 memory:90710000-90713fff  


For what it's worth, I have the same Dell 11 3000 series computer, with the same configuration output you display above. I had the same problem with speakers not working when I was running Ubuntu Live from the USB (though the headphones did work). Once I installed Ubuntu (alongside Windows 8.1) the speakers worked fine without me having to do anything.
