HDMI and LCD
#11
We can make the audio works via HDMI by modifying the audio_policy.conf in /etc (rooted image) : change default_output_device (Global Configuration) to: AUDIO_DEVICE_OUT_AUX_DIGITAL.
At that time the audio works both of HDMI and 3.5mm jack
Does anyone know how to boot while hdmi is connected ? (LCD Image). Please share.

We are currently working with Allwinner on the boot while HDMI is connected on the LCD image build. Getting close but still not ready for release.

I've not had any luck with dual and hdmi audio. Tried every image and got dual video. That was easy, but would not play the audio. Would love to see this one come true.

#1: Use Linux (Ubuntu, Debian, or any other) and maybe re-mount your microsd card as writable.
#2: Change the file in Android itself, if your image is rooted.

it is always possible to fit a small llinux distro on a usb flash drive. when you need to do work on sd card just boot to that and you will have no problem editing the file. also, you can now install certain drivers on a windows box to allow reading/writing some linux filesystems. read this if you have time,

  Tried a lot of these things and toasted my laptop. Had to reload the OS and some nasty virus's in them as well. I have a rooted image now but still won't let me write a read_only file. Still researching thru the emulator app and other stuff. I keep plugging away. Smile

jeepers!, it might actually be a good time to create a small usb linux install and stop getting beat up by windows. when things get that crazy it's usually a sign from the computer gods that it is time for some changes. i tell ya what did it for me was microsoft pushing the updates out too fast and they would muck things up beyond repair. just consider all the time you waste. i know it sounds like something awful from what you describe. i keep one win 10 around for my epson inkjet and samsung laser printer cause those 2 companies still have not figured out how to control their printers from linux. yup, that fastlane b.s. was what led me to the exit sign. give it some thought. if you mean android rooted, you need to use pine64 5.1 from last july if you want write capability cause every build since then by any dev just did not work for me as far as filesystem write. .ymmv .

The Android 6 released build can output HDMI and LCD simultaneously.
