Gioele Barabucci, could you please test the latest mainline kernel (not the daily) via http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.12-rc6-saucy/ and advise to the results?
As well, because Samsung does not easily reveal what the latest BIOS is for this model, could you please download the latest firmware software as per http://www.samsung.com/uk/support/model/NP900X3D-A03IT-downloads, and advise if a BIOS update is available? If so, when you update to this, does it change anything? If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1213719 Title: [Samsung NP900X3D-A03IT] Powertop shows 100% Device Usage for audio codecs Status in “linux” package in Ubuntu: Incomplete Bug description: On my Samsung Series 9 NP900X3D-A03IT despite setting the PowerTOP -> Tunables setting for: Bad Enable Audio codec power management to: Good Enable Audio codec power management PowerTOP reports that the two audio codecs are both up 100% of the time, even when no sound is playing: 100,0% Audio codec hwC0D0: Realtek 100,0% Audio codec hwC0D3: Intel ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.5.0-37-generic 3.5.0-37.58~precise1 ProcVersionSignature: Ubuntu 3.5.0-37.58~precise1-generic 3.5.7.16 Uname: Linux 3.5.0-37-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25.
