    How does AVS speech request fail from "wiced_audio_init"?

    ykj

      While I test AVS in WICED Studio 5.01 using BCM943909WCD1, it fails to start speech request and logs "wiced_audio_init returns 4" as below message.

      =============

      For triggering speech request, I push the button, SW4(PLAY/PAUSE).

      What is the cause of this failure and how I can correct it?
