Audio output low volume

  • Hello


    I started checking the PicocomA7 modul on the evaluation board for some basic tests.


    One part was the audio output and input which failed due to a very low volume.


    Using arecord and an external audio source seems to be ok.

    Running aplay with a well known wave file shows nearly nothing on the output pins.


    As it's the same audio codec like the PicocomA5 may be its the same issue like it was few years ago.

    Best regards

  • Hi,


    do you have changed the software on your evaluation board, if yes which release do you are using?


    Can you send me the debug log from the board and also the commands which you have used?

  • Hi,


    I can´t reproduce the issue which you have mentioned. Can you please do two more tests.


    • Run command "speakertest -c 2 -t wav". How is the sound now?
    • Can you install the release software and do the tests again. Is there any change?
