2.6.23-rc5, I have stereo speakers plugged into the left/right output.
I never moved the speaker plug. The volume gets louder when I load the
new kernel.

It looks like the name of the main PCM channel changed from 'pcm' to
'PCM" too. I had to reset my levels in alsamixer. I have a STAC9227.

I have everything working. It just all needed to be readjusted. Plus
now I have to have my amp (powered speakers) set at a much higher
level than before.
