The kernel at http://people.canonical.com/~henrix/lp1013183/ didn't work on my HP dv7-2270us (laptop).
Sound was fine with 2.6 kernels (Ubuntu 10.04, Debian Squeeze), and was working with Ubuntu 12.04 kernels 3.2.0-2{3,4}-generic (with 3.2.0-24 sound would stop after being suspended several times; 3.2.0-2{3,4} both have poor sound compared to 2.6.x).
