All these things wrong. I've tried once again to figure out influence any changes in file skypeaudiocodecs.conf. I've done 'cat /dev/random >skypeaudiocodecs.conf'. As you know its file got binary. After that I killed all skyhost processes. And do you know? It works as nothing has happened. It seems to me there is only way to communicate with skype company or developers. There is no another way!
