I have a problem with natty kernel, that is I have audio ouput working, but input not working. This problem didn't exist with 2.6.36 kernel.
I am sure that the microphone is not muted; alsa-info.sh output is attached. I've tried to run `arecord test.wav' and the resulting wave pack file is just some little noise.
My Ubuntu installation is Lucid amd64, and I've upgraded the following packages (listing sources) to natty version:
alsa-driver 1.0.23+dfsg-2ubuntu1
alsa-utils 1.0.23-3ubuntu1
linux 2.6.37-5.14
linux-firmware 1.40
linux-meta 2.6.37.5.7
nvidia-common 0.2.24
nvidia-graphics-drivers 260.19.06-0ubuntu1
nvidia-settings 260.19.06-0ubuntu1
This problem didn't exist at least in 2.6.36-1.7, but nether 2.6.37-2.10 nor 2.6.37-3.11 nor 2.6.37-5.14 works for me. Other versions between 2.6.36-1.7 and 2.6.37-2.10 are not tested.
All source packages except linux are just copied from natty release archive and rebuilt on Lucid in a PPA (ppa:happyaron/sandbox, sorry for there are other unrelated packages).
The linux packages were built with `skipabi' and `skipmoudules' rules.
