AOSP doesn't seem to support .mkv file extension (but still supports matroska container) so rename to .mp4 first. HEVC 10-bit i.e. 'H.265 Main 10 Profile' doesn't seem to play currently. Edit. Main 10 Profile fixed so also this will be working if/when there's new releases.

Jellyfish Bitrate Test Files

A collection of .mkv video clips encoded at various bitrates; useful for testing the network streaming and playback performance of media streamers & HTPCs.

Is there any Raspberry Pi 400 owners out there who have encountered the HDMI audio problem where the sound stops working system wide ? It seems to be affecting me really bad. I didn't think the system was over heating or super maxed out, this can happen just by navigation

If there's any logs needed I can certainly try to provide them, just let me know how

Secondly. Assuming this is no easy fix, what is the next best way to provide audio to a modern Sony TV ? How do you use the 3.5mm output that supposedly is not affected on a TV set?

Thanks very much!

Edit - guess I didn't look before posting. No audio jack on Pi 400

I have set this SD card aside and am going to go back to Raspberry Pi OS for now. I absolutely love the idea of running Android on it and will be the first one back as soon as the issue is resolved. But I'd mark this as not working on Raspberry Pi 400 as I'd consider HDMI audio to be mandatory functionality

I will anxiously be watching for a fix

You're welcome to fix this anytime.

There's been one similar report on Sony Bravia TV (https://konstakang.com/devices/rpi4/LineageOS19-ATV/#comment-6080895434) so try with a different TV/display. I don't have any hardware I could use to reproduce such issue, whatever that may be, and you haven't provided any useful information (logcat, dmesg) to even figure that part out.

I am a novice user, my apologies since you seem offended in some way!

I do not think it's related to Sony Bravia, I'm back on Raspberry Pi OS and it's working perfectly, I can't imagine Sony Bravia being the root cause of anything but I am happy to confirm the issue on another TV. I am quite positive it would happen regardless of device!

Regarding the logs, I already mentioned I would be happy to provide them. I don't know how!

I sincerely appreciate your work and your assistance, my apologies if it seemed like anything otherwise. Once your build has working audio as good as Raspberry Pi OS, I would never use anything else again. I definitely want this fixed. The difference in sound is instantly evident, though. Even just from clicking around - there's not a single "lost click" in movement anywhere, I never noticed how severe it was in the Android build until going back to Raspberry Pi OS and hearing the difference

I wasn't offended.

As it was explained to you elsewhere, the way HDMI audio is implemented on builds with Linux kernel >=5.10 (i.e. Android 12 and above) is because Pi Foundation chose to use IEC958 format for HDMI audio which is not supported on Android. Raspberry Pi is not an Android device to begin with and Android is not your regular Linux distribution. This discussion would also be easier for everyone else to follow if you hadn't spread it to several different topics on several different forums (my site, here at XDA, and Raspberry Pi forum). You don't get any more attention by doing that, it's actually the total opposite. So for future reference, make one single structured post where you properly describe the issue you're having and attach appropriate logs that might help to figure out the cause of the issue.

You can capture logs by e.g. typing in 'logcat' and 'dmesg' in shell (ADB/SSH/serial console/some third party terminal app/etc).

Hi Konsta. I installed the latest aosp version for rpi4. install nikgapps and everything is ok.

i have a xbox cloud account and installed the Game Pass App from google play store.

My problem is xbox original controller is not sync with bluetooth ...

When i try to pair a new device, the xbox controller appears on android screen, i click to sync but something happens that the android refreshs the screen and nothing happens...

logcat?

I don't have any hardware to test. Android 13 switched to new gabeldorsche bluetooth stack and there's reports of some other bluetooth issues as well. You could also try if this is any different on Android 12 builds.

@KonstaT , i attached a logcat debug.

While the logcat was enabled on adb, i tried to sync the Xbox S Controller (Bluetooth)

 

[leonardopires]

The next step is try android 12....

@KonstaT , the Xbox S Controller is pairing with android aosp 12L....

This looks similar to what I've seen before. Will see if I have some bluetooth device I can reproduce this with.

@KonstaT , the Xbox S Controller is pairing with android aosp 12L....

Yes, like said, most likely something related to the new bluetooth stack introduced in Android 13.

Hi @KonstaT

I installed AOSP13-20230130-KonstaKANG-rpi4.zip

How do I get remote access VNC Mac? What is the default password?

ADB and SSH worked easily.

Thank you!!

Its worked in VNC Viewer App. No password. Disable encryption.

I would like to thank for this great project. I got my rpi4 yesterday, installed AOSP 13, but bluetooth gamepad wont connect, any fix for this? thanks

Discussed earlier on this same page (https://forum.xda-developers.com/t/...raspberry-pi-4-b.4481977/page-4#post-88109253 and forward).

If this is critical for you, you can use Android 12 releases for now.

I also would like to ask how to fix cut off of audio in HDMI? Thanks

HDMI audio on builds with Linux kernel >=5.10 (i.e. Android 12 and above) has been discussed e.g. http://disq.us/p/2r2wh1w

This should be fixed if/when there are new releases (https://github.com/raspberry-vanilla/android_device_brcm_rpi4/pull/1).

Thanks
