do you mean your computer chassis does not have front audio panel or
your front audio panel does not support jack detection ? http://www.intel.com/support/motherboards/desktop/sb/cs-015851.htm http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#standards 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 Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1090421 Title: [GA-MA785GM-US2H, Realtek ALC889A, Green Line Out, Rear] No sound at all Status in “alsa-driver” package in Ubuntu: New Bug description: firefox browser cant play radio(online radio) music ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-34.53-generic 3.2.33 Uname: Linux 3.2.0-34-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
