Hello -- I've been trying to get my sound working for nearly a month now with no luck.
* I've followed the Gentoo ALSA Guide *several times*, and it's not working for me. * I've already unmuted my card in alsamixer and raised the volume to 100% * There is no sound that is coming from any of the following: -- mplayer (movies or mp3's) -- speaker-test -- flash movies in Firefox -- etc ... i.e. NOTHING gives me any sound * But when I try to play sound in any of the above mentioned programs, I get no errors (i.e. they seem to think that my sound *is* working. * I've checked to make sure that the volume isn't muted via the keyboard, and that the volume is at 100% there too. * There are no errors that are popping up in /var/log/messages or /var/ log/dmesg when I do '/etc/init.d/alsasound restart' nor when I manually rmmod/modprobe the sound modules * The hardware is not damaged/broken -- it works fine from Windows * I've tried to disable ati-hdmi in the kernel and it doesn't make a difference (it's currently enabled, but unused according to lspci -k) and according to http://kmuto.jp/debian/hcl/ the ATI HDMI card should be using snd-hda-intel (as it currently is) anyway * I've tried telling alsaconf to use the Intel HDA card, and the ATI HDMI card -- neither of these work. * I started a thread on Gentoo Forums regarding this problem () and someone said: <QUOTE> HD Audio often needs a model option passed to it based on the codec see /usr/src/linux/Documentation/sound/alsa/HD- Audio-Models.txt to see what the model should be. </QUOTE> ... But looking through that file, I could not determine which option I should use (if this is even a solution, anyway) for my card. Google was no help here. (note that the Intel HDA card uses the SigmaTel ID 76a0 codec) Is there any additional information I can provide (besides what I just mentioned, and the stuff below) to help diagnose this? Anything else I should try? Any help would be *very* much appreciated. Thanks, Jesse Taylor P.S.
