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. I am keeping them around should I do any other testing with them. laurynas@laurynas-ThinkPad-T410:~/Downloads$ ls -l *.deb -rw-rw-r-- 1 laurynas laurynas 11298080 2011-10-18 20:29 linux-headers-3.1.0-0301rc10_3.1.0-0301rc10.201110181253_all.deb -rw-rw-r-- 1 laurynas laurynas 897630 2011-10-18 20:29 linux-headers-3.1.0-0301rc10-generic_3.1.0-0301rc10.201110181253_amd64.deb -rw-rw-r-- 1 laurynas laurynas 11295418 2011-10-18 20:33 linux-headers-3.1.0-999_3.1.0-999.201110171146_all.deb -rw-rw-r-- 1 laurynas laurynas 898358 2011-10-18 20:32 linux-headers-3.1.0-999-generic_3.1.0-999.201110171146_amd64.deb -rw-rw-r-- 1 laurynas laurynas 37052966 2011-10-18 20:27 linux-image-3.1.0-0301rc10-generic_3.1.0-0301rc10.201110181253_amd64.deb -rw-rw-r-- 1 laurynas laurynas 37008344 2011-10-18 20:33 linux-image-3.1.0-999-generic_3.1.0-999.201110171146_amd64.deb -- 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
