Both the speaker amp and the headphone jack are tied to the HP output pins. While the speaker is mono, the headset jack is stereo. Unfortunately the driver does not support automatic switching of this. In addition, the headset is DC coupled, or "direct drive" enabled. The headset's microphone is tied to MIC2 with HBIAS providing power. A separate internal microphone is tied to MIC1 with MBIAS providing power.
