I've tried installing the high definition audio codec from http://www.realtek.com.tw/downloads/downloadsview.aspx?langid=1&pfid=24&level=4&conn=3&downtypeid=3 (LinuxPkg_5.16rc14.tar.bz2) but still not working.
 This actually removed everything that was in hardware, input and output in the audio configuration panel: I have now only the "dummy output"
