    Hello,
    I have OnePlus A6013 with OxygenOS 10.3.2

    I try to stream music in my car with usb-c otg cable to Helix DSP.3 (i have that USB Interface card installed in my dsp)

    It's not working. I try to find advices here and youtube but i didn't find any good solutions.

    In youtube solution was that you must activate developer tools and then change your usb configuration.

    In this video there was these options to choose:

    -Charging
    -MTP (Media Transfer Protocol)
    -PTP (Picture Transfer Protocol)
    -RNDIS (USB Ethernet)
    -Audio Source
    -MIDI

    In my phone there is only options:
    -File Transfer
    -USB tethering
    -MIDI
    -PTP
    -No data transfer

    How i can use my phone with Helix DSP.3? Where i can find that Audio Source option?

    Has this option been removed by some OS update?

    -Tipi
