'Speaker' Object has no atrribute X Error with Core2

  • M

    Hi everyone, I recently attended a workshop where Core2 was used via flow.m5stack.com, the speaker of the device was used in that workshop.
    I now got myself a device now and burned it with UIFlow_Core2 v1.13.2.
    I connected to the device using API Key and want to issue some sound via the Speaker but am getting error speaker object has no attribute sing() or setVolume().

    The flow I am using is setup --> PlayTone. What I need to do do enable the speaker?
