The A23 Q8 tablets have an internal mono speaker w/ external amp which has a shutdown control tied to a GPIO pin. 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.
