I have the same exact problem, it started a few weeks ago saying that soundmax needed to be reinstalled because the hardware configuration had changed. So I looked around online, unintalled soundmax, wouldn't reinstall saying that I have missing hardware.
I ran the thinkpad update utility and then ran the soundmax utility again and it actually worked!
Now.... my computer bluescreened randomly like it does sometimes when it's loading up a game like cod4 and I restarted it, had the same "soundmax needs to be reinstalled because the hardware configuration had changed" message waiting for me with no sound when Windows came back up. Nothing that I can do/find will fix this? This seems to be a common problem with soundmax drivers, you'd think they would fix this or at the very least offer a real driver, not just an install package?
Just a few things I've tried:
1)the soundmax driver always says "Installation Failed! The audio driver files do not support your computer hardware" regardless of what I do.
2)system restore doesn't find a difference between versions of my system with and without sound.(haven't tried a full restore from backup, not worth it yet
3)my system still detects "bluetooth handsfree audio device" so I wonder if that may have something to do with it, but haven't found anything online
4)I've tried installing every "high def" audio patch that I could find and restarting, all to no avail
5)also installing the correct intel chipset, didn't work either.
6)thinkpad update and windows update tell me that my system is up to date
edit... I also have T61, bought it mid July and haven't had a major problem until this
