Here is a status of this problem on my laptop with the latest quantal updates. I have attached powertop's HTML output. What I find confusing is that audio devices are listed both at 100% and 0% usage in the same powertop run:
100.0% PCI Device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller 100.0% PCI Device: Advanced Micro Devices [AMD] nee ATI RV635 HDMI Audio [Radeon HD 3600 Series] [...] 0.0% Audio codec hwC0D0: Analog Devices 0.0% Audio codec hwC0D1: LSI Can somebody explain this ? ** Attachment added: "Powertop HTML output" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/877560/+attachment/3380878/+files/PowerTOP.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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
