Hi ,  

As you mention, audio input seems to not depend on 4a. But my result of toay, I think 4a affect audio input.

HW : M3 Starter Kit only (without KF)
SW : master

  • Steps:

  1. Bootup and connect your microphone into CN9 on Starter Kit.

  2. Remove 4a-hal json file from /usr/libexe/agl/4a-ha/etc/

  3. Re-boot by push SW8 button.

  4. set capture volume to 10% using alsamixer
    $alsamixer -c 1

  5. After boot up, run the followings command.
    $ arecord -D hw:1 -t wav -d 5  -r 44100 -f S24_LE hoge.wav -c 2
    or
    $ arecord -D hw:1 -r 44100 -f S24_LE -c 2 | aplay -D hw:1
     

Won't Fix
