Try the very latest Linus git tree.  A couple of fixes for Dell laptops are in after rc7.

If it still doesn't work, try sound git tree (master branch)

Anyway, please run alsa-info.sh with --no-upload option and attach the generated file.  This will contain more detailed hardware information.  The script is found at:

This is the requested info. I'd prefer to stick with rc's when possible. They're on-the-edge enough for me as I'm running rc7 on a "production" laptop.

Then try rc8 released yesterday :)
