[SOLVED] Asus G51 notebook sound and keyboard fix 9.04 and 9.10

http://ubuntuforums.org – I have a Asus G51 VX here with the ICH9 (82801I) for audio. Under 9.04 and 9.10, the ALSA drivers work. But I didn't get any sound. However, when I plugged in my headphones halfway, the sound worked but only for one channel. Fully plugged in, there was no sound at all. So in order to get the headphone jack working properly, I made the following edit: Code: gedit /etc/modprobe.d/alsa-base.conf then add or edit the last line to: Code: options snd-hda-intel model=asus-mode3 Save and reboot (or force an ALSA reload) for the change to take effect. The source came from http://forum.notebookreview.com/show....php?p=5097834 and I'm sure many Asus notebook owners will be able to get some sort of sound working with this fix, regardless of the model. I have yet to try all the possible modes available off that link. Here's his list: Code: ALC662/663 ==========   3stack-dig    3-stack (2-channel) with SPDIF   3stack-6ch    3-stack (6-channel)   3stack-6ch-dig 3-stack (6-channel) with SPDIF   6stack-dig    6-stack with SPDIF   lenovo-101e    Lenovo laptop   eeepc-p701    ASUS Eeepc P701   eeepc-ep20    ASUS Eeepc EP20   ecs          ECS/Foxconn mobo   m51va        ASUS M51VA   g71v          ASUS G71V   h13          ASUS H13   g50v          ASUS G50V   asus-mode1    ASUS   asus-mode2    ASUS   asus-mode3    ASUS   asus-mode4    ASUS   asus-mode5    ASUS   asus-mode6    ASUS  auto          auto-config reading BIOS (default) I'm not certain "asus-mode3" is the best choice for the G51. I will cycle through them all this weekend to see which works with a) the headphone jack, b) the speakers, c) the microphone jack, and d) the line-in jack. The other item not listed is the headphone jack switch that enables/disables the speakers when the headphones are plugged/unplugged. As a side note, the backslash/bar key doesn't work upon install. It returns the less/greater instead. To fix this, I found one at http://crunchbanglinux.org/forums/to...yboard-layout/ where he suggests this: Code: xmodmap -e "keycode 94 = backslash bar" Hope ths helps! (Hardware)
