Description of problem: /var/log/messages contains this: ... kernel: hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... ... Version-Release number of selected component (if applicable): Current (2008-10-21) rawhide: kernel-2.6.27.3-27.rc1.fc10.i686 How reproducible: Always. Actual results: AFAICT, despite of the warning, at least basic sound features seems to work, but I haven't tried to check in depth, because other sound-issues have been interfering with recent rawhide. Additional info: # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 # lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This warning happens on _every_ board that isn't specifically listed in ALSA driver (and only those that have buggy BIOSes are listed). If it works, this isn't a problem.

I call this broken design. > If it works, this isn't a problem. A false warning is a bug, whether you like this or not - period. Reopening.
This bug will likely go unnoticed here (by Takashi Iwai or anyone else who would make a releveant change). You should report it to alsa-devel mailing list if you want to see it fixed.

Great, another example of a non-cooperational maintainer who trying to push around users upstream - Please understand that I consider maintainers who expose this kind of attitude to be a miscast and recommend you to quit Fedora.
OK, I will report it for you and even make a patch if you suggest a better (i.e. less confusing) message in place of this one. Something like... kernel: hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... kernel: hda_codec: Notice: there is a great chance that everything will work correctly regardless. kernel: hda_codec: Notice: the above message means only that your board isn't specifically listed in ALSA driver. Having every board in existence whitelisted would be insane.
Fixed upstream, and explained in detail in Documentation/sound/alsa/HD-Audio.txt. Fedora will pick it with new kernel. Closing.
