This bug also affects the Sony Vaio VPCF11M1E, which uses the same chipset, Realtek ID 275.

I'm using the default alsa-1.0.20.1 package from the repository. Installing the following packages fixed the internal speakers problem for me.
linux-backports-modules-alsa-2.6.31-20-generic (2.6.31-20.22)
linux-backports-modules-alsa-karmic-generic (2.6.31.20.33)

But there is still no sound from the microphone.
