did your computer chassis have a hda front audio panel ? How to identify your desktop board audio codec The Technical Product Specification (TPS) for each Intel® Desktop Board will indicate whether your board supports AC’97 or Intel® HD Audio. To find the TPS for your board: Go to Intel® Desktop Board page. Select your desktop board. Click Product Documentation in the left-hand navigation channel. Select Technical Product Specification. Refer to Front Panel Audio Header Pinouts for additional onboard header pinout information. How to identify your front panel audio solution codec To identify your front panel audio solution’s audio codec, refer to the specifications or documentation for your PC chassis or front panel module. Note that AC’97 and Intel® HD Audio front panel solutions are different and may not be directly compatible or interchangeable. You can also physically check the audio cable of the front panel audio solution. If there is a cable connected to Pin 4, you have an Intel® HD Audio module; if there is no cable to Pin 4, you have an AC97 module. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066062 Title: [quantal] Sound volume changes without user interaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1066062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
