I am not here to beat people up. What bugs me is that I take my time to detail a
problem, and then people answer as if they only read the title. I say it's possible,
and they expound on why it is impossible. But guys, it is possible, I just showed
you it is. There's no need to waste time on this contention. It is possible.
Well, why I think the way I think.
I've been googling high and low. I figured out neither Microsoft nor SoundMAX have
bothered to expose this option in their graphical interface, although the hardware
of the sound card enables this, and it's possible to control it through code (as
we know from the ALSA implementation on Linux).
So, what should be the hack for my Thinkpad T61. All the discussions I could find
about disabling the internal speakers through a registry hack, referred to Macs.
And all of them originate from what this guy came up with:
http://forum.onmac.net/showthread.php?t=1239
If you read that thread, he says he used a trial an error tactic.
Ok let's see. The registry entry for his Mac is {4D36E96C-E325-11CE-BFC1-08002BE10318}
Will it be the same on my Thinkpad? Yes! How do I know? I went to where the SoundMax
driver is on my system: C:\DRIVERS\WIN\Audio\SMAXWDM\W2K_XP\ADIHdAud.inf
You can see it here:

And what is there on the 15th line? Same ID.
Yayyyy!
So I guess this registry entry is used on my Win XP for storing the sound card info
as well.
Ok. So I go to that entry in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}

It's not exactly the same as in the Mac guy's scenario. But some things are similar.
It seems as if all the interesting stuff is in the 0005 entry. How do I go on from
here? He said trial and error.
Hmmm.... and he also said "Finally, go to Device Manager and disable then enable
the "Sigmatel High Definition Audio CODEC" driver so that it reads the new configuration
in."
What should I do in my case? I have different hardware.
Here is the picture of my device manager:

I would appreciate your help, comments, insights.... as long as you actually read
what I write.
