This has nothing to do with SOF, the main issue is that the amplifier needs to be configured by HDAudio verbs which are translated by the HDaudio codec in I2C commands. The problem is to reverse-engineer what those verbs might be, usually with a Windows setup. There was a Wiki for this sort of things, see https://thesofproject.github.io/latest/getting_started/intel_debug/suggestions.html#reverse-engineer-the-windows-audio-driver
