[Bug 877560] Re: Audio codec draining power when not in use
Gioele Barabucci, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

It's been a while since I reported this, now this machine has received kernel/BIOS/RAM/rest of ubuntu package upgrades, and I cannot reproduce the apparent audio codec power hog with powertop. OTOH, now it's fixated on unused ethernet card, reporting that it is taking 15-16W. Of course all powertop suggestions were followed. I run powerstat anyway: Running for 300 seconds (30 samples at 10 second intervals).

[Bug 877560] Re: Audio codec draining power when not in use
So the basic issues here are that we need to get accurate and consistent power measurements that we know are reliable. I suggest running powerstat from my PPA: https://launchpad.net/~colin- king/+archive/powermanagement * Make sure the machine is not running any unnecessary power sucking applications (like webpages with flash) etc * Run powerstat - it will take ~8 minutes so that we can get a long battery capacity change to get a more accurate measurement. ..and then we can start looking seeing if this is really as bad as powertop reports. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/877560 Title: Audio codec draining power when not in use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/877560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 877560] Re: Audio codec draining power when not in use
I have installed a custom kernel for an unrelated issue and applied all the released package updates and the powertop report has changed. The kernel is from bug 844957 : http://people.canonical.com/~ogasawara/lp844957/ Now the powertop reports 0 mW for the sound codec, and the overall battery drain reported is lower too (although not by 3.3W lower). OTOH meanwhile I have found bug 834725, so I am not sure how much powertop reports can be trusted. Later I will reboot back to official kernel to check if it is kernel or package updates that have caused this change. ** Attachment added: "powertop report with pkg updates and bug 844957 testing kernel" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/877560/+attachment/2560178/+files/powertop-3.0.0-13-generic-0W.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/877560 Title: Audio codec draining power when not in use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/877560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have done the following: 1) Removed the proprietary nvidia drivers 2) Installed RC and daily kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-rc10-oneiric/ and http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ 3) For each of these ran powertop on idle system. The reported wattage varies 1.4W-1.7W (originally was 1.6W), in all cases the codecs are shown as being used 100% of time. I am attaching the powertop reports. The reports always shows 1W while GUI shows 1.4-1.7, I include the GUI value in the file name. I didn't re-run appport for these kernels, please let me know if I should.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the release candidate kernel versus the daily build. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream-testing' text. Please let us know your results.
