When the "HiFi Quad DAC" is disabled, like the diagram I posted suggests, the Snapdragon CPU SoC handles the audio signal including MQA. Please view the diagram as it closely displays how each DAC operates. As I have stated, I confirm the operation of the ES9218P DAC SoC. The Quad DAC operates in full balanced mode internally before output to single ended stereo minijack. As for the power output stage, again the diagram displays the paths and the Integrated power management processor within the ES9218P SoC maps the automatic gain control based on impedance of headphones. If treated as a line output device, this same power management processor activates the line out mode providing a stable 2VRMS from a 3.6V battery supply.
See I'm confused now. CSG is sayin' that if u shut off the Quad DAC, then only one of the ESS DACs are being used. But then yklee is sayin' that if u disable Quad DAC that the only DAC being used is the Snapdragon one. And u guys wonder why ppl get confused? lol
