I have already run alsamixer many times and tried every combination of muted and unmuted settings with all volumes maximized. With no volume settings muted, and all volume settings at maximum level, I still get no sound. Everything *looks* like it's working - output in the kernel log, xmms's display, everything. But I get no sound out of the built-in speaker or the headphone jack. I have tried the following: * Default install of Fedora Core 3; it recognized the sound card and installed module settings in /etc/modprobe.conf to load snd-intel8x0. But I never got any sound out of this default install no matter what I tried. * Custom compiled the 2.6.9 kernel with no patches except the software suspend 2 patch. This built the version of the ALSA drivers that come with 2.6.9. Still no sound. * Downloaded and compiled version 1.0.7 of the ALSA drivers and installed them. Still no sound. ====================================================================== ---------------------------------------------------------------------- bji - 11-30-04 08:56 ---------------------------------------------------------------------- Unfortunately, the patch did not fix the problem. I applied the patch by running the following commands: cd ~/alsa-driver-1.0.7/alsa-kernel patch -p1 < ~/stac9752a.diff cd ~/alsa-driver-1.0.7 make make install This patched, built and installed new snd-ac97-codec.ko and snd-ak4531-codec.ko modiles. However, when I modprobe -r the old versions and modprobe the new versions, I still received no sound from the built-in speaker or the headphone jack. I also ran alsamixer and played with the settings there, especially the headphone and the line out settings. No changes to these values had any effect. Is there something else I can try :( Thank you for taking the time to try to solve this problem, I really do appreciate it! ---------------------------------------------------------------------- tiwai - 11-30-04 21:02 ---------------------------------------------------------------------- One thing you can check is to set the capture source as 'Mix', and record the sound during playback PCM at the same time. In this way, at least you can see whether the PCM is processed correctly in the AC97 codec (e.g. you can see waves in a sound editor). If the signal is processed properly in the chip, it's a problem of some missing configuration for the HP or Line-Out jacks.
