Additional info:
Comment 1 Tom Brinkman 2007-07-28 10:47:35 EDT 
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
Comment 2 Martin Stransky 2007-07-30 04:13:49 EDT 
so this line:

options snd-hda-intel model=thinkpad  # I added this

has no effect, right?
Comment 3 Tom Brinkman 2007-07-30 09:49:01 EDT 
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
Comment 4 Martin Stransky 2007-07-30 09:56:35 EDT 
T61 isn't supported in ALSA yet, you need add some extra patches to alsa-drivers.
Comment 5 Tom Brinkman 2007-07-30 12:41:18 EDT 
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?
Comment 6 Martin Stransky 2007-07-31 03:20:09 EDT 
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).
Comment 7 Tom Brinkman 2007-07-31 19:46:33 EDT 
   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?
Comment 8 Martin Stransky 2007-08-01 04:01:47 EDT 
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.
Comment 9 Martin Stransky 2007-08-01 04:04:24 EDT 
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.
Comment 11 Marek Mahut 2007-08-01 06:55:14 EDT 
I can confirm that the sound is working fine on this laptop using patched alsa
module.
Comment 12 Tom Brinkman 2007-08-01 11:30:07 EDT 
    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.
Comment 13 Tom Brinkman 2007-08-04 15:16:26 EDT 
  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.
Comment 14 Martin Stransky 2007-08-06 04:31:06 EDT 
okay, closing.
Comment 15 Joel Uckelman 2007-08-07 06:51:19 EDT 
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?
Comment 16 Martin Stransky 2007-08-07 06:55:50 EDT 
yes, kernel.
Comment 17 Joel Uckelman 2007-08-07 13:24:50 EDT 
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!
Comment 18 Jan Hutař 2007-10-20 18:40:35 EDT 
Please note (this took me some time):
