Audio over USB not working

    When I connect my phone to my car's head unit using USB, I am unable to play music from my phone. I was able to do this on my OnePlus 3T (which I just upgraded from) no problem.

    And when you connect the phone, do you pick a choice from the menu? Charge only, mtp, midi, etc? Does a menu appear?

    a menu appears, changing it to anything other than charge only doesn't do anything and it changes itself back to charge only within a couple of seconds.

    Try to go to developer options, and set default to mtp.

    actually this wouldn't work, as I'm not trying to play music stored on my phone's internal storage, but instead through the Spotify app

    i confirm the same issue.

    on android 8 when i was connected with USB at the radio (pioneer mvh-190ubg) the audio of any app (youtube - spotify, ecc) was routed automatically trough USB. Now when the usb is connected the audio output is trough the phone speaker.

    the only thing that i didn't try is if in the audio menu (from the volume slider) it appears USB audio. i'll try later.

    3T had a headphone jack. Had you used that one to stream music to your car? Or have you always used the USB port?

    Now that's very strange. My 2015 Nissan does not support at all audio through USB. My wife's 2017 Ford allows file transfer (aka MTP), so it can play music stored on the phone. But none of them play through USB directly. How does your phone "see" the car? As a charger or as a computer?

    What brand, year and model?

    it's a pioneer head unit, I don't know how the phone sees it but the audio should play how I described

    When you pull the notifications, there could be one "Android System", that only pops up if the phone is connected to a computer or a device smart enough to act as a USB host. Or, if there's no notification, it connects for audio via USB only. But this is digital audio, requiring a compatible DAC somewhere external to the phone (I think).

    My suggestion is to use the USB-jack adapter that came with the phone.

    I'll have a look, but using the jack adapter is not a good enough solution, I want the phone to charge at the same time like my 3T did, I also can't change songs using the head unit if I use the jack adapter.

    In such case, use bluetooth. You'll be able to stream, control music and charge at the same time. If your head unit does not have bluetooth (I doubt it), you can use an adapter like this:
