The mixer DAPM is suitable than the mux DAPM for the analog microphone registers(0x05, 0x06) because each bit for path is switchable.
I'm not sure about this one.
The TRM has this for the ANAMICL register: Analog microphone left: Main microphone, headset microphone, carkit microphone, or auxiliary left microphone can be routed to the input of the A/D converters separately (only one enable bit at 1).
It is true, that it does not states explicitly that you can not set more than 1 bit, but it has this: only one enable bit at 1...
Are you sure about this?
I read it at TRM too, but cannot believe it such mixer of outputs.
Actually, i setted to 1 both HSMIC_EN bit and MAINMIC_EN bit for the ANAMICL register, and recorded sound from headset mic and main mic. The result is that both sounds are recorded.
So, to be sure this part, can you inquire about it to TI side?
