After migrate from ubuntu 12.04.1 to 12.04.2, no ALSA devices from snd-bt87x because driver lost the functionality of load_all parameter.
Here is a patch to fix this: http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-3.8.y&id=146a89dcb2cbc032cdd36e656252410980b4aa04.
