Try reinstall the system language...
You are maybe using some russian audio kext as base? Cuz they are just names and can be edited in the audio plist(s).
First of all, thanks for the answers.
There is not any problem with the system language. I am agree with midi opinion. I had used this kext base (DummyHDA.kext)
I have been revising the plist´s file, but I do not know what do I have to correct.
I will attach my DummyHDA, modified by myself, if anybody wants to check it.
