Audio device gets recreated on every USB connection

[JeDaYoshi]

Even if usbaudio is not running or anything, now an audio device is created on my system everytime I plug in my phone. Audio gets forwarded to here as normal, but I'd expect it to not create the device when not asked, just when using usbaudio. Well, I find some cases where it'd be convenient to just use this, but I also want to know a way to make this not happen.

This happens even after reboots.

This is not expected.

USBaudio just sends a request to change the mode: https://source.android.com/devices/accessories/aoa2
But then, it should be "reset" on unplug.

What is the result of lsusb for your device?

It was just "Google Inc.", which is how it appears when being used as Audio Source.

Well, I had to change it manually from the Developer options, as it wasn't getting reset on unplug/reboot, and I had an issue where it was not making any sound on the speakers even if unplugged, being that the reason.

Normally:

Bus 002 Device 052: ID 1bbb:903a T & A Mobile Phones

With Audio Source (it was always getting like that, and I noticed the input in PulseAudio):

Bus 002 Device 053: ID 18d1:2d03 Google Inc.

Just for reference, my phone is an Alcatel CAMEOX (5044R), running Android 7.0.
