Description Ralf Corsepius 2008-10-21 04:04:39 UTC

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.

Comment 1 Bug Zapper 2008-11-26 04:04:24 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

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.

Do you call this proper operation? I call this broken design.

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.

Comment 6 Vedran Miletić 2009-08-27 08:27:34 UTC

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.

Comment 7 Vedran Miletić 2009-09-06 17:26:40 UTC

Fixed upstream, and explained in detail in Documentation/sound/alsa/HD-Audio.txt. Fedora will pick it with new kernel.

Closing.
