here is the output of dmesg:

As I do not have much experience in this. I have asked the Actions how to do it.
So you want have an opition in the Android Setting, so that you can choose the audio output to HDMI audio, Audio Jack or USB DAC, right?

Now in Android, it will automatically detect the earphone, and when the earphone plug in, it will route the sound to earphone automatically, or it will use HDMI audio.

I also will help to google some tips. And I found the Android 5.0 support the USB DAC

Tony, hi.

I just wanna have working usb-audio-autoroute - default function on android 5.x.

On many-many android-devices what i have tested - autoroute is already working OK.

So you want have an opition in the Android Setting, so that you can choose the audio output to HDMI audio, Audio Jack or USB DAC, right?

Any additional options in the android settings - i no need. I need just standard android 5.0 future - usb audio autoroute.
