I have a Thinkpad T40, which includes the Thinkpad Embedded Controller. The Thinkpad EC has an external, non-driver dependent volume control known as the Thinkpad Audio Control.

I'm running KDE 4.4.5, with kmix 3.6, and kernel 2.6.35-gentoo-r10.

I used to have my sound system built in. In order to get a USB speaker to work, I upgraded my kernel and switched everything to modules.

Since doing that, I no longer have the Thinkpad Audio Control as a tab in kmix. The device is loading. I see it in alsamixer, and it works. It doesn't seem to matter what user I do this under.

What do I have to do to get the TAC to appear in kmix?

Here, for background:
