Last modified: 2007-11-30 17:12:11 EST
Description of problem: No sound, Thinkpad T61, AD1984 snd chip Version-Release number of selected component (if applicable): alsa-lib-1.0.14-0.4.fc8 How reproducible: no sound since first install F7-live (6/27), then updated to rawhide an kept current daily Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Sound should work. Tests in kcontrol, sound system never produce sound 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) Thinkpad T61, AD1984 chip A net search of 'linux ad1984' reveals that the patches (3) for this chip should be in current alsa (>= rc4) Additional info:
Forgot; alsa-utils-1.0.14-0.7.fc8 modprobe.conf: alias snd-card-0 snd-hda-intel options snd-card-0 index=0 options snd-hda-intel index=0 options snd-hda-intel model=thinkpad # I added this
so this line: options snd-hda-intel model=thinkpad # I added this has no effect, right?
Correct, options snd-hda-intel model=thinkpad has no effect. I should add I had to manually upgrade alsa-utils-1.0.14-0.7.fc8 alsa-lib-1.0.14-0.4.fc8 using rpm as yum only returned "nothing to do". Updated from alsa-lib-1.0.14-0.4.rc3.fc7, alsa-utils-1.0.14-0.7.rc2.fc7
T61 isn't supported in ALSA yet, you need add some extra patches to alsa-drivers.
According to, http://www.alsa-project.org/changes/v1-0-14rc4--v1-0-14.txt "- hda-codec - Add AD1884 / AD1984 codec support Added the support of AD1884 and AD1984 codec chips. Also experimental quirks for Thinkpad T61/X61 laptops with AD1984." "- hda-codec - Fix wrong mixer controls for AD1984 thinkpad model Fixed the wrong mixer controls for AD1984 thinkpad model." ... it is. Will F8 support T61/AD1984?
You can check the 1.0.14 drivers (how-to is here - http://people.redhat.com/stransky/alsa/) but they still don't work well).
Isn't this y'alls pursuit. IE, "you need add some extra patches to alsa-drivers." Didn't you mean "we", Fedora ?? That was the reason for my filin a BZ to begin with ? My question stands unanswered, Will F8 support T61/AD1984?
We use the official ALSA drivers released by ALSA project (the latest are 1.0.14). So if ALSA releases drivers which work fine with AD1984, Fedora (8 or whatever) will use them and it will support AD1984, too.
Please note this line from changelog: "Also experimental quirks for Thinkpad T61/X61 laptops with AD1984." it's just an experimental support which will be improved in new drivers.

I can confirm that the sound is working fine on this laptop using patched alsa module.
I have sound. I'M the idiot, it's mostly a PEBKAC. Tho I had been to thinkwiki (fedora), I read Martin's 'ubuntu' link. Then dug an old headphone out of storage an plugged into the external jack. Sound works very well. It's just the built in speakers that don't work. Which is also covered at Martin's link. Usin kmix I can't get them enabled, but I'd just as soon use external sound anyhow. I've since plugged an woofer/satelites system in. I didn't need any of the patches. Rawhide alsa-libs an -utils provide workin sound for T61/AD1984 an kernel's hda-intel. Sorry for wastin y'alls time, an thanks for your patience an attention.
Recent rawide updates, most likely alsa-utils-1.0.14-1.fc8 alsa-lib-1.0.14-1.fc8... I've discovered that now the onboard speakers work when the external jack is unplugged. T61/AD1984 is fully supported.
okay, closing.
I tried those versions of alsa-utils and alsa-lib from Rawhide on my T61 with no success. Is there some other package additionally which needs to be updated?
yes, kernel.
Thanks! I can confirm that sound works on my T61 after installing: kernel-2.6.23-0.71.rc2.fc8 alsa-lib-1.0.14-1.fc8 alsa-utils-1.0.14-1.fc8 Wonderful!
