Sorry, I'm newer to FSL board, some problem might seems easy, but i am still confused. now, we have a imx6q sabreauto reference board installed with Android 4.3. i have done such operation, but found there is no sound output:
1) open "Sound Recorder" apk
2) plug in microphone in J26-1 (mics-in), connected to CS42888 AIN3+/AIN3-
3) start to record and speak toward to microphone for a moment.
4) stop record and play the record file, but I cannot hear any sound output ( however, i can hear audio if playing the music in SD card).
Analog signale waveform can be masured input to CS42888 AIN3+/AIN3- with oscilloscope, if speak more loundly toward microphone, the waveform will be changed, it seems microphone works well.
Could somebody kindly help me? many many thx ^^
