No audio input available on PC

  • I have installed DATV express for Pluto on an ASUS i7 mini pc to be used portable.
    I connected a webcam on USB and selected this for video.
    installation and drivers are ok but on start express reports configuration error

    NO AUDIO CAPTURE DEVICE CONFIGURED 0


    This PC has no audio input hardware; only realtek audio out.
    i do not need audio, but DATV express does not allow this.
    The program starts but PTT is greyed out


    any options to bypass this ?
