Hello All
I am new to Audio driver.
I used NanoPC-T4 and Android 8.1 running (20190718 baseline cloned from gitlab oreo).
My team made a custom RK3399 board based on NanoPC-T4.
Differences are only from eMMC and Microphone. The original T4 boards does not support Headset Microphone.
But we connected headset microphone as well as Internal Mic on our own board.
My test result is the recording does not work. However The headset's button click seems be input according to sound level floating in voice recording android app after I changed 5651 initial reg value regarding Rec Mixer mut/unmute register. I manually unmute the Bst3's path with increased gain value. headphone mic jack is connected to IN3P.
My test scenario is below.
1. When headset is connected, The headset microphone is used.
2. When headset is disconnected, The internal microphone is used.
I tried to change DTS and RT5651.c code. But could not figure out the solution.
Does anyone have the answer about Headset Microphone Recording use case?
How to modify rt5651 routing or control ?
Please give your kind comments. I focused on this few days. But could not find answer.
thanks.
Regards, JK
