Problem is still present in kernel-2.6.25-0.54.rc2.fc9.x86_64 Tried to compile Alsa 1.0.16 drivers and replace the ones in the kernel, but the drivers won't compile on rawhide, compiler is more picky. kernel-2.6.25-0.64.rc2.git5.fc9.x86_64 exhibits same problem kernel-2.6.25-0.65.rc2.git7.fc9.x86_64 also exhibits the same problem. However, I found that if I upgraded alsa-drv from 1.0.16rc2 to 1.0.16 the problem with the audio was fixed. I did have to make some simple patches to alsa-drv 1.0.16 (commenting out comparisons to current->fs->root) So please upgrade alsa-drv in kernel to 1.0.16 I did have to set model=asus-dig2 in modprobe.conf to make sure alsa was using the right model driver for my card. kernel-2.6.25-0.69.rc3.git1.fc9.x86_64 exhibits same problem. Again upgrading Alsa to 1.0.16 final fixes the problem of the sound card not working. Is anyone even reading this report? yes, there are just a lot more bugs than there are people to work on them unfortunately. I'll forward this on to the upstream alsa developers. thanks for taking the time to debug this as far as you have, it's very helpful. Just an FYI, but 2.6.25-0.82.rc3.git2.fc9 still has broken sound still. Again upgrading alsa to 1.0.16 final fixes it. rc3-git2 had the latest round of ALSA updates applied, too:

Chuck, is there any additional info you would like me to provide? I found this tool to be quite helpful http://hg.alsa-project.org/alsa/raw-file/e167861901c7/alsa-info.sh Might want to see if that is still reporting alsa-drv version 1.0.16rc2 or 1.0.16 This is what alsa-info looks like when the driver is working correctly. http://pastebin.ca/926351 I just booted into the new kernel (2.6.25-0.87.rc3.git4.fc9) and since the sound didn't work in it either. I thought I would run alsa-info.sh before I installed the known working drivers and after. The main thing I found in this is that the broken kernel is still reporting an alsa version of 1.0.16rc2 for the alsa-drv portion. Alsa-drver final was released on 2-06 and rc2 was released on 1-29. Anyway we can get the final release of the driver pushed into the mainline kernel. At least before Fedora freezes start to happen. Created attachment 296733 [details]

Status update: Still broken in kernel-2.6.25-0.105.rc5.fc9.x86_64, same fix still works. Apparently the fix is in the -mm tree. Don't know why it hasn't been merged in. Status update: Still broken in kernel-2.6.25-0.150.rc6.git7.fc9.i686, same fix still works. Had to switch my machine from 64bit to 32bit for other reasons kernel-2.6.25-0.161.rc7.fc9.i686 Based on a tip from the Fedora Test mailing list I set options snd-hda-intel index=0 model=asus-dig2 power_save=0 in /etc/modprobe.conf prior to this, I did not have power_save=0 in the file after adding that the sound card worked properly. So I also recommend that this be a default setting for the snd-hda-intel driver. Changed the default to 0 (disabled.) (In reply to comment #16) > Changed the default to 0 (disabled.) FWIW, I strongly dislike this fix. Alsa's power_save mode can save quite an amount of power and thus my notebook's battery can last a bit longer. So I think there is more then one problem report needed to justify disabling power_save for everyone. Especially if a real fix seems to be in -mm and alsa 1.0.16 Kevin, when you built the ALSA modules yourself, what values did you set for CONFIG_SND_HDA_POWER_SAVE and CONFIG_SND_HDA_POWER_SAVE_DEFAULT? Whatever the defaults are... This is the command I used to compile... ./configure --prefix=/usr --with-cards=hda-intel --with-sequencer=yes So maybe off is default?

Especially if a real fix seems to be in -mm and alsa 1.0.16 It's not disabled, just off by default. You can enable it by adding: power_save=1 to the module options for snd_hda_intel. *** Bug 405741 has been marked as a duplicate of this bug. *** Just a note - I've re-enabled the HDA powersave (at 5s) in rawhide, it'd be great to get some feedback on how this is working at this point. I'm currently running Fedora 10, can I just install the kernel from rawhide? Or is there other stuff I would need to install. I just don't want to pull in too much of rawhide. You could just test it on your current kernel by: echo 5 > /sys/module/snd_hda_intel/parameters/power_save -Eric FYI, I'm running 2.6.29-0.6.rc3.fc10.x86_64 since a few days with "options snd-hda-intel power_save=1" in modprobe.d/audio and it works really well (Dell Latitude D630, GM965) Since this bug was originally about device recognition, and is now closed, if people could put information regarding pop/click & powersave problems in this driver over in bug 493972.
