On this same motherboard (Gigabyte GA-MA74GMT-S2), I had success getting the front panel input to work by adding the following line to /etc/pulse/default.pa
load-module module-alsa-source device=hw:0,0 I added this just before the udev auto-detect module: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect .else Then run: /etc/init.d/pulseaudio restart If you still get no sound input: 1. Run alsamixer 2. Press F4 to go to the Capture screen 3. Right Arrow over to the "Input Source" column 4. Press Up/Down Arrow until the "Front Mic" input is selected 5. Make sure your Capture volume is all the way up (adjust Mic Boost to taste but beware if it's too high you'll get distortion) -- 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/1004829 Title: [GA-MA74GMT-S2, Realtek ALC887-VD, Pink Mic, Front] No sound at all Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: Mic doesn't work on Ubuntu 12.04 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-24.39-generic 3.2.16 Uname: Linux 3.2.0-24-generic x86_64 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
