[android-porting] Disable USB Audio Routing Programmaticaly

[PW]

Hi, I'm wondering if there is a way to disable USB AUDIO ROUTING on nougat.
I did it in lower api via reflection and setwireddeviceconnectionstate.
This however doesn't seem to want to work on nougat and i'm not sure if the
reflection has changed at all.

I want exclusive access on USB output and do not want system notifications
to go via USB as they interrupt the signal.

Thanks

At one time there was a setting for this, and there may still be but I seem
to recall it has suffered from bit rot and does not work as well as it used
to.
Search source code in frameworks/base and packages/apps/Settings for all
references to the symbol
USB_AUDIO_AUTOMATIC_ROUTING_DISABLED and then follow the bread crumbs from
there.
Please update here with anything you find, as I am curious too.
