White Screen

[danbulant]

Issue

Yet another white screen issue :)

Hardware

Device	Connection Method	Screen	Mobile Device	Android Auto Version
Raspberry Pi 4 8GB	USB Cable	Waveshare touchscreen 10.1'	Xiaomi redmi note 10 pro	10.9.634644 (the app) ; 1.7 (based on logs from dash)

Installation Method: Install.sh

Description of problem:

White screen, no errors in console.
Audio playback via bluetooth works, phone detects it correctly, in console, I can see that it connected and started receiving data correctly, but no output is shown.

Expected Result:

Working android auto screen

Problem-relevant steps to reproduce:

1. Fix issues regarding new rpi os version (flashed latest rpios image, today) based on Support for Ubuntu 22.04 #127 until it compiles
2. Change video codecs as needed (tried v4l2 (the default) and openh264dec (based on the issue, I added it myself to the code, hopefully correctly))

Additional info:

I tried changing the codecs as well as their order

I see "Selecting the openh264dec h264 decoder", so maybe that worked?
I have no errors in console, the only errors I got was no audio device before I connected something to the jack, but that fixed all errors in console. And audio playback via bluetooth works.
Sometimes when I disconnect and reconnect I get aasdk error code 30 or 10, but that seems to be just a simple "disconnected" thing.

I tried disabling RtAudio, which also shows a white screen but also stops the stream (well, it seems the whole AA app quits) after few seconds.

I'm new to low level stuff, android dev and got the raspberry pi just a few days ago, so I don't know much about how to debug it well.

Logs

full logs, incl disconnect

Apologies for the necro, but I am pretty sure I had audio with a white screen until I disabled RTAudio. Not 100% positive, but I seem to remember being able to hear my music.

Apologies for the necro too lol, but can confirm a similar behavior that audio worked for a bit after RTAudio was disabled to fix the white screen bug.

I believe restarting the system may have borked audio after that, will try #151 (comment) and keep yall updated.

12/1/2024 UPDATE:
Not starting dash as a service method seems to be a work around as seen in #131 (comment). By starting it as a command/shortcut, no whitescreen and RT Audio can be switched on.

@TheWolf95 I was having the same issue and after tinkering with a few methods and multiple reinstalls the method I finally got to work for me was changing how dash auto-starts. I started with the service method and noticed the issue however the issue wasn't present for running Dash via cli. So I started playing with auto-start / auto-run methods and the way that works for me is to create a file at /etc/xdg/autostart/run.desktop with the following contents:

[Desktop Entry]
Name=Dash
Exec=/home/pi/dash/bin/dash

Note: I am running on RPI 4 4GB with Bullseye 64bit. I am not using the Lite edition as I ran into far more problems and opted to disable some services and use various other optimizations I found on blog posts and hackaday articles to speed up boot.

I don't know if this helps find the underlying issue with RtAudio or not but this is how I got it to work without disabling it.
