Hi Sam. If the above doesn't change anything on your T60 for the sounds, there
are a couple of options I can suggest, both of which I've tried, and work.
Not on a T60 admittadly, but on an Asus M2N-X Plus mobo, with hda intel
Azalia soundcard.
So to work, and this is the first thing I tried. Add the following line
to /etc/apt/sources.list.
deb ftp://musix.ourproject.org/pub/musix/deb/ ./
All you want from the above repo is a kernel, and the one I installed has alsa
driver 1.0.16, which resolved my problem, and may resolve yours.
Next, do an apt-get update, then open synaptic. The kernel I installed was, as
below.
linux-image-2.6.26.2-rt1-libre1
Having installed this kernel, make sure to go back into /etc/apt/sources.list,
and comment out the musix repo line, by putting a # at the start of the line.
I cannot stress this enough, as if you do an apt-get dist-upgrade with the
musix repo still active, you could possibly find packages being updated from
the musix repo, and oftentimes can cause problems.
Ok. Now the new kernel is installed, reboot using your newly installed
kernel, and see if your sounds are working any better than before.
Moving on to option 2, simply upgrade the alsa driver. Many patches have been
added to the alsa driver since 1.0.12rc1, particularly with reference to the
snd-hda-intel module, so go to the link below, and download alsa driver
1.0.17, which is the current stable version.
http://alsa-project.org/main/index.php/Main_Page
I'd suggest creating a new folder in your /home/user directory for this Alsa
stuff. I simply name mine Alsa-drivers, and download all the Alsa packages
into this folder/directory.
You now need to install some packages, so as to get your newly downloaded alsa
driver built, and installed.
Su to root on the CLI, and open synaptic, and install the following packages.
build-essential
kernel-package
linux-headers-2.6.18-6
That done, close synaptic,and run apt-get install linux-headers-$(uname -r)
This will install the headers for your kernel.
Now to build, and install the 1.0.17 alsa driver.
As user, cd to where you downloaded the driver, then do:
tar xjvf alsa-driver-1.0.17.tar.bz2
A new folder/directory has now been created, so do:
cd alsa-driver-1.0.17
Now type: ./configure, and when that runs to completion, type: make, which may
take some time. When make completes, with hopefully no errors, su to root,
and type make install. If all has gone well, and after a reboot, (using the
Etch kernel, not the musix one, if you've also installed that) running
cat /proc/asound/version should now show the alsa driver as 1.0.17.
Now you may, or may not have better control of sounds on your T60.
I don't have a Lenovo T60 laptop, so these are only suggestions given with the
hope that they may be of some help in resolving your problem.
You asked where I'd found the model options for the AD1981 codec. I assume you
have downloaded the 1.0.17 driver, and unpacked it using tar xjvf, which
creates a new folder/directory. Click on the new directory, then on
alsa-kernel, then Documentation, then ALSA-Configuration.txt.
All the best.
Nigel.
