I've got no time to read the whole thread, since I need to repair my
mixer. However, for a full preempt non-rt kernel there is no patch
required. It only depends to the config of a vanilla kernel.

Regarding to the CONFIG options in the previous post, there are some
CONFIG options missing, but those are already set for e.g. the
lowlatency kernel for Ubuntu Studio precise.
