I recently updated my kernel from 2.5.69 (ALSA 0.9.2) to 2.6.0-test9

alsa-base and alsa-utils (debian packages).
Keith, There have been a lot of fixes to the Via and Intel chipsets recently, although there are still quite a number of people having trouble. Consider ~x86 and go to Alsa-1.0.0rc2 (or whatever is offered at this point. I haven't heard of that many people running 2.6 series kernels, but most of us on 2.4 kernels are, I think, working fairly well with this 1.0 pre-release.
I updated my 2.6.0 kernel to the latest ALSA release (1.0.1), and also updated alsa-utils to 1.0.1, and I still have no sound. As before, the drivers all load without errors and every app thinks it's playing sound just fine, but nothing comes out. It is basically behaving as if it is permanently muted, even though I have tried just about everything with the mixer settings.
Also as before, I can still get sound just fine on a 2.5 kernel running ALSA 0.9.2 on the same box. One thing that I noticed is that alsactl and asound.state are numbering my controls starting at 3, are missing two controls, and list the controls in a different order compared to the mixer settings when running on 2.5/0.9.2. Maybe the card capabilities are no longer being detected properly? Below is a comparison of the asound.state between the two instances:
