[Chetan Rajpal]

why settings still crashing on your build but not on rt android build?? what rt android has changed in settings app?? do you know anything about it?

[Sahaj Sarup]

Rt uses their own settings app
https://github.com/RTAndroid/android_packages_apps_Settings
Aosp settings crashes but we don't know why.

[Chetan Rajpal]

Ok... I wanna ask one more thing does audio work on 7.1?? Also, is there any way to speed up boot cause every time I boot it takes 10mins on samsung evo sd card.. I am using your tablet build of marshmallow...

[Thien Pow Chong]

10min is too long for pi3, maybe you need another microSD card with Class10

7.0 has no audio, they got uploaded the binary here
http://www.mediafire.com/download/dw5kunz5w03k0cq/and7rpi2016-08-25.img.tar.bz2

7.1 not sure, i am still trying to do the source code repo sync.  and nobody uploaded a binary yet.

[Thien Pow Chong]

did the 7.1 build from source
checked the kernel, there's no sound driver in it, is it normal?

[Igor Kalkov]

Maybe the sound is missing just because nobody had time to enable it? :D

I don't use other distributions for RPi, so I can't compare. But maybe it is as easy as turning it on in the kernel config?

m = "module"

RTAndroid builds would probably include all of those kernel modules, but they are not loaded by default. We can do some experiments on that. Other distributions usually don't include modules.

Could you please check how this is done on Raspbian or something similar? If we know which config option(s) is/are relevant, we could just change them to "y".

Great job! Let me know if you get sound with this config.

[WalkOnATYCLB]

I'm very much interested too. I always watch this group. Good job guys :)

[drraj...@gmail.com]

Ok this seems to be intresting nice job... I'll too try it..

[Thien Pow Chong]

why it can't put in final.config when doing the merge?


Value requested for CONFIG_SND_BCM2835 not in final .config

Requested value:  CONFIG_SND_BCM2835=y

Actual value:

[Thien Pow Chong]

final .config file is found in kernel/rpi folder as hidden file

 

[Thien Pow Chong]

found another parameter that is required but not in the defconfig

CONFIG_SND_ARM=y

this is a must have too.

[Igor Kalkov]

Good job! You can try setting the value manually after the merge tool (before compilation)

[Thien Pow Chong]

just a little script to share with those who is building from source.
can save this script as copyBOOTSys.sh as shown in the pic and put it into the folder structure as RTAndroid.  then you can utilize the RTAndroid's install script to install after copying files.

#!/bin/bash

AndroidSrcPath="/media/thienpow/Backup/Android7Src"

copyfiles()
{
    echo " delete old files..."
    rm -rf boot
    rm system.img

    echo " creating folders..."
    mkdir -p boot/overlays

    echo " copying files..."
    cp -a "$AndroidSrcPath/device/brcm/rpi3/boot/" .
    cp "$AndroidSrcPath/kernel/rpi/arch/arm/boot/zImage" boot
    cp "$AndroidSrcPath/kernel/rpi/arch/arm/boot/dts/bcm2710-rpi-3-b.dtb" boot
    cp "$AndroidSrcPath/kernel/rpi/arch/arm/boot/dts/overlays/vc4-kms-v3d.dtbo" boot/overlays

    cp "$AndroidSrcPath/out/target/product/rpi3/ramdisk.img" boot

    cp "$AndroidSrcPath/out/target/product/rpi3/system.img" .
}

copyfiles
echo "All done. "

[WalkOnATYCLB]

Does this mean this new image your making will allow sound in 3.5 jack and official Raspberry pi touch screen support?

[Igor Kalkov]

It would be nice to get any kind of sound first, let's keep the steps small.

Here is a list of sound-related modules loaded by default on Raspbian:

kernel/sound/arm/snd-bcm2835.ko
Alsa driver for BCM2835

kernel/sound/core/snd.so
Advanced Linux Sound Architecture driver for soundcards

kernel/sound/core/snd-pcm.ko

Midlevel PCM code for ALSA

kernel/sound/core/snd-timer.so

ALSA timer interface

[Thien Pow Chong]

i am adding what Igor has suggested too now.
below is what is not there before

CONFIG_SND_PCM=y

CONFIG_SND_TIMER=y

also i am modifying the audio_policy.conf which can be found in device/brcm/rpi3

global_configuration {
  attached_output_devices AUDIO_DEVICE_OUT_SPEAKER
  default_output_device AUDIO_DEVICE_OUT_SPEAKER
}


audio_hw_modules {
  primary {
    outputs {
      primary {
        sampling_rates 48000
        channel_masks AUDIO_CHANNEL_OUT_STEREO
        formats AUDIO_FORMAT_PCM_16_BIT
        devices AUDIO_DEVICE_OUT_SPEAKER
        flags AUDIO_OUTPUT_FLAG_PRIMARY
      }
      hdmi {
        sampling_rates 44100|48000
        channel_masks dynamic
        formats AUDIO_FORMAT_PCM_16_BIT
        devices AUDIO_DEVICE_OUT_AUX_DIGITAL
        flags AUDIO_OUTPUT_FLAG_DIRECT
      }
    }
  }
}

not sure if it works.

hate the 4 hours per make... my pc too slow.

[Igor Kalkov]

Not sure if this is relevant, but found these lines in the logcat:

01-01 00:00:32.908   436   436 I SystemServer: StartWiredAccessoryManager
01-01 00:00:32.910   436   436 W WiredAccessoryManager: This kernel does not have wired headset support
01-01 00:00:32.911   436   436 W WiredAccessoryManager: This kernel does not have usb audio support
01-01 00:00:32.911   436   436 W WiredAccessoryManager: This kernel does not have HDMI audio support

[Thien Pow Chong]

can use "make menuconfig" in kernel/rpi folder to check which driver is loaded into the kernel

from the peyo source, sound and gpio was not loaded as built in driver for kernel.
so if your touch screen was connected via gpio then it might not work but if connected via usb, it should work out of the box bcos the mice and touchscreen driver was included.

[Thien Pow Chong]

yes, hdmi audio is not loaded into the kernel.

[Igor Kalkov]

Did you get audio working by enabling this option?

[Thien Pow Chong]

not tested yet. will try to dig more first...

anyway to build faster?

after changing a few config, rebuild for 4 hours already... :'(

[Igor Kalkov]

RAM / SSD / CPU are crucial. Are you building the kernel only or the full platform?

On my machine kernel compilation takes about 5 minutes. The full platform about 1 hour.

[Thien Pow Chong]

i am changing another pc. it's just crazy have to wait all day.

[ubunt...@gmail.com]

Hi folks,

I have tested all the trial and error cases Thein and Igor have suggested, but still couldn't get the audio :(..

Still I could see the logcat logs as below,

01-01 00:01:05.248   400   400 W WiredAccessoryManager: This kernel does not have wired headset support

01-01 00:01:05.249   400   400 W WiredAccessoryManager: This kernel does not have usb audio support

01-01 00:01:05.249   400   400 W WiredAccessoryManager: This kernel does not have HDMI audio support 

Anything else which we can try? If anyone can give pointers then i would try, test and share the results as i have faster PC.

Thanks

there are some stanza/settings have to be added to the rpi3.mk but i am not sure what is it...

if you have fast internet too can try download the banana pi source code and see how they load the hdmi and sound at the .mk
ftp://pub:bana...@dev.banana-pi.org.cn/Source_Code/bpi2/BPI-M2-Android4.4.tar.gz

[Thien Pow Chong]

just found someone tried on the mk file

https://github.com/android-raspi/android_device_broadcom_rpi3/blob/aosp-7.1/device.mk
look at the line 85 onwards.

and he has a custom boot mk with modules/driver install 
https://github.com/android-raspi/android_device_broadcom_rpi3/blob/aosp-7.1/custombootimg.mk

[ubunt...@gmail.com]

Thanks for the inputs, will try and let u guys know.

[Thien Pow Chong]

found another suspect

android.hardware.audio.pro

this should included to 
rpi3_core_hardware.xml

[Igor Kalkov]

Good finding! Are you building it already or should I test it next days?

[ubunt...@gmail.com]

I tried adding android.hardware.audio.pro to rpi3_core_hardware.xml. Compiled and tested but still the audio doesn't work!

Anyone got success?

[Thien Pow Chong]

found 1 more suspect

i looked into the differences of the android 6 and android 7

android 6 local_manifests has the following 2 lines

<project path="hardware/amlogic/audio" name="hardware_amlogic_audio" revision="master" remote="peyo"/> <project path="hardware/amlogic/libstagefrighthw" name="hardware_amlogic_libstagefrighthw" revision="marshmallow" remote="peyo"/> hopefully this is the very last missing part.

[Thien Pow Chong]

sorry 2 more lines that is required... din't see it earlier. <remove-project name="platform/external/tinyalsa" /> <project path="external/tinyalsa" name="external_tinyalsa" revision="marshmallow" remote="peyo" />

[Thien Pow Chong]

but to make a correct config of these lines you can't simply copy and paste, bcos android 7 local_manifest point to the remote at https://github.com/codewalkerster
<remote name="hk" fetch="https://github.com/codewalkerster"/>
from there can find repo which is similar:

android_hardware_amlogic_libstagefrighthw
android_hardware_amlogic_audio
android_hardware_alsa_sound
android_external_alsa-utils
android_external_alsa-lib

so it should be config as example below:
<project path="android/hardware/amlogic/audio" name="android_hardware_amlogic_audio" revision="master" remote="hk"/> and so on as the list above...

something like that...

[Thien Pow Chong]

sorry my suggestion has some error... bcos revision should be more specific to point to s905_5.1.1_master
and the path should just remove android
correct example: 

<project path="hardware/amlogic/audio" name="android_hardware_amlogic_audio" revision="s905_5.1.1_master" remote="hk"/> 

[Thien Pow Chong]

btw, someone might want to test using mali driver with gpu support instead of software rendering... 
not sure if it's working... https://github.com/codewalkerster/android_hardware_arm_gpu/tree/s905_5.1.1_master/mali

[Thien Pow Chong]

for display driver... look into these 2...

android_hardware_arm_gpu
android_hardware_amlogic_mali

[Thien Pow Chong]

below are needed in BoardConfig.mk if you want to use the 3.5 audio jack. BOARD_USES_I2S_AUDIO := true #if you are using hifiBerry card for 120db BOARD_USES_PCM_AUDIO := true #analog, regular speaker BOARD_USES_SPDIF_AUDIO := true #if connect to hifi with RCA.. red/white output.

Hello

how possible to run webview or install app on this version?

Hi,

I changed few kernel configurations and

I could see following serial messages on my board at start up,

[    4.070258] ALSA device list:

[    4.070263]   #0: Dummy 1

[    4.070268]   #1: Loopback 1

[    4.070272]   #2: bcm2835 ALSA

something can be derived from this?

[ZPOW]

peyo's kernel_rpi is not updated.  from the bcm2709_defconfig

last updated date is Aug.

while the official rpi-4.4.y last updated is 15 days ago.
https://github.com/raspberrypi/linux/blob/rpi-4.4.y/arch/arm/configs/bcm2709_defconfig

i think it could be the firmware doesn't match the kernel source

You know if you already have the appropriate settings to get the audio in raspberry with Android 7.X.

Thank you all and very grateful for your work.

Hello Jag,

Do I understand this correctly, do you have working HDMI or 3.5mm Jack sound on the RTAndroid release with some settings?

Do you might want to share these settings?

Hi all,

I just pushed a workaround for the audio issue on Nougat, see here: https://github.com/peyo-hd/device_brcm_rpi3/pull/52

[Igor Kalkov]

Does it fix HDMI or audio jack?

[neilcu...@googlemail.com]

Android-Things uses a different overlay for the sound:

dtoverlay=pwn-2chan-with-clk,pin=18,func=2,pin2=13,func2=4

I will try this out tomorrow

[Igor Kalkov]

Great, thanks. Please keep up up-to-date.

[neilcu...@googlemail.com]

Done some reading, this appears to be for directing audio to the GPIO pins.

On a side note - I updated from 20161208 to 20161214 and appeared to lose the App Draw button.

[Igor Kalkov]

Google has redesigned the Launcher. Depending on your screen you have to swipe from the bottom to see the app drawer.

[approx4...@gmail.com]

As I said on the PR. I wanted to mention that here as well. This .so file can be copied to the respective folder in RTAndroid (and probably the other Nougat ROMs, too) to enable HDMI audio. That's a very nice catch. Thanks a lot.

That would be:
https://github.com/secuflag/device_brcm_rpi3/blob/429b332cc1ace266eeb13ccd1e17f08a3d10f960/audio.primary.rpi3.so?raw=true
to "system/lib/hw/" on the system partition.

[louisru...@gmail.com]

Confirmed HDMI Audio works on rtandroid-aosp--7.1-20161224-rpi3.zip with workaround .so file.

Thanks for your work, guys. I don't like the idea of copying binary files, but your finding brought me on the right track and we fixed the audio issue in the most recent build.

[approx4...@gmail.com]

Awesome! I find it really impressive, that the RPi3 is able to run a much newer version of android than the vast majority of android devices on the market. And open source solutions contribute to keeping it this way. So thanks.

I believe that working audio will make it more interesting to many more people, resulting in a bigger community and more development over all. I've been excited about the earlier android experiments back on the older raspberries, only to be disappointed when those blog entries were never updated after a few months. And it seems that the raspberry pi android repository at Google https://android.googlesource.com/device/pifoundation/rpi3/ was intented for Android Things all along, however I do not think this IoT OS does the raw power of the RPi3 justice. Since the RPi3 will probably not be superseded by a RPi4 in the near Future https://www.raspberrypi.org/help/faqs/#generalFuture the efforts can be concentrated on this device, without the dreadful "The device 'n' is dead! Long live device 'n+1'!" scenario. I hope this effort stays alive for the next few android releases to come.

It doesn't work for me. No audio at all! Is there anything I can try to get it to work. Any specific settings in the config.txt perhaps?

[approx4...@gmail.com]

This works on my LG Flatron W2261VP:

hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=1
hdmi_mode=16

[maurice...@gmail.com]

I currently have the issue that it worked on my computer screen with audio, but when I connect the raspberry Pi to my car Stereo the screen displays a green stripe and it does not fill the entire screen, also the audio does not work on my car stereo. See picture below for info, if I need to upload some debugging information, please let me know what and where to find it. the car stereo I am using is the folowing (the link is dutch, could not find the english version...): http://www.kenwood.nl/car/navigatie_multimedia/mulimedia/DNR8025BT/?view=details

Are you using the audio jack? I don't know whether it's operational - for now only the HDMI audio is working.

What kind of screen are you using?

[maurice...@gmail.com]

I am using HDMI audio on the car stereo: http://www.kenwood-electronics.co.uk/car/nav_mm/mm/DNR8025BT/

it has a 800x640 pixels screen. I removed all couplers and it is now a directly connected without extensions, I also tried disabling the overscan, but still the green stripe with no audio.

hdmi_group 2
hdmi_mode 7

buildprop also changed to the apropiate resolution.

[Igor Kalkov]

Well, the green stripe (no idea what that is!) and the audio are separate issues. Does your device generally supports HDMI audio (did you test it in other setups)?

[maurice...@gmail.com]

the chromecast version 1 works like a charm with the sound and video 😉

[maurice...@gmail.com]

So I ust finished fixing the resolution, I connected my Linux laptop to it and found it could handle a much larger resolution then expected:

and gave the following settings in config.txt (build.prop resolution is 1280x720)

hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=1
hdmi_mode=4
disable_overscan=1
config_hdmi_boost=5
kernel=zImage
device_tree=bcm2710-rpi-3-b.dtb

initramfs ramdisk.img 0x01f00000
mask_gpu_interrupt0=0x400
avoid_warnings=2
gpu_mem=256
enable_uart=1

The image is still a little out of the screen (left and top, but overscan cannot fix this) but this is not a big point for me, it works great :D

My biggest problem is the sound ;)
Is there any way for me to get the sound working, can I get some information like the logging of the resolution to find out if there are protocols which are not supported on the raspberry pi? Or does someone know what goes wrong?

[Igor Kalkov]

Well, if the HDMI audio is working with other devices, I really don't know why it doesn't work with this one.

Does this device have a separate audio input? You could use the audio jack instead.

Regarding the logs, if you can connect it to network, you can pull ADB and/or kernel logs.

[ZPOW]

1. how many speaker on your car?
2. check if your original 2din connected to "amplifier".

if you have many speaker and the 2din do not connect to any amplifier, then the pi wont provide enough power to the speaker to generate sound.  you need to connect an amplifier to the speaker, then from the pi audio to the amplifier.

The 2din is not connected to an external amplifier, but it has an internal one, the chromecast does also not have the capability to provide the correct strength to ¨amplify¨ this much. On the other hand, neither does the HDMI cable have that capability. All the sound that goes through HDMI is digital and the ¨receiver¨ can convert this to it's internal, or external amplifier. So I think that the digital sound connection through HDMI goes wrong somewhere (it can be possible that the raspbery pi want's to communicate using a protocol that is maybe to new for the car stereo?). For the record, my car has in the front: 2 tweeters and 2 mid-speakers/subwoofers and in the back 2 tweeters and one subwoofer with an own amplifier, which get's the signal from the rear tweeters, so 6 speakers on the internal amplifier.

Below is the message log, do you know if there are other logs which can contain more information about this, and where can I find them :) ?
I could not find an direct error for the sound problem, but there are a lot of ¨no such file or directory¨, is this normal or are you guys working on this?

Also, I tested sound from my laptop to the car stereo, and that works also.
I just came across the logcat, here are the logs: http://pastebin.com/24H6sjH8

Is it normal to have the following line in the logging?:

Sorry, I have no idea why the HDMI audio doesn't work with your stereo, but does work with a monitor :-/

Yeah, on my monitors (IIyama ProLite E2473HS) it works fine.

Did you check the audio jack while connected to your car stereo (you have to change the configuration first - please read the FAQ at our homepage)? Just to make sure the audio is actually there and it is probably the HDMI-(format?) issue.

[maurice...@gmail.com]

I will try this tonight, also I will try the sound with another raspberry pi with another OS, maybe it's the raspberry pi itself ( I hope not :( ).

I just tried the folowing things on two raspberry pi 3's:
raspberry pi with NOOBS:
- HDMI sound, works
- 3.5mm sound, works
Raspberry pi with RT Android 7.1 (build after sound fix, and the latest build):
- HDMI sound, does not work
- 3.5mm sound, works (but this is such a huge workaround, that I don't want to be permenent, it requires a lot of switching between my inputs on the car stereo)

Sorry, I have no clue what might be causing this. Maybe some kind of HDMI type mismatch (PCM / Bitstream / MHL) - unfortunately I don't know much about those.

[maurice...@gmail.com]

I just ruled out the power source, by using the exact powersupply I am using on the screen (I used a very long power extension cord :P ).
I pretty much ruled out every config.txt setting, those look like they don't do much:

hdmi_group=1
hdmi_mode=4

I also tested another bitrate in the system/etc/audio_policy.conf (44100), no luck there, it works on the TV/Screen, but not on the car stereo. I tried to get some info with tvservice on raspian with the following result, but I do not know if those are supported with this Android:
