    Default MTM800E no audio output

    Hi everyone.

    I have a problem with a Moto MTM800E that i use as a dmo link and svxlink. I use an R1 2020 sound card like the one on this page https://vktetra.com/build-your-own-g...-to-the-radio/

    The raspi detects the sound card and the 3.3 volt ftdi cable. I receive TG conversations and SDS command reports, but when i transmit with a portable radio, no audio comes out through the MTM800E.

    Anyone know what the problem could be?

    I have the external output through the rear connector configured in the codeplug.

    Thanks

    Alex
