And how about my questions in the previous mail? Does
i915_audio_component_get_eld() is called and returns 0?
And is monitor_present set true or false?
If i915_audio_component_get_eld() is called but returns zero, track
the code flow there. It means either intel_encoder is NULL or
intel_dig_port->audio_connector is NULL.
