[DEV-only][WIP] ALSA BCM21553 Audio libs built from source - BroadcomCM

I've created this thread to join developers into the final audio fix for android 2.3.7. Although the prupose of this thread is to fix Audio on Android 4.0.4 we first need audio drivers source.
On all our based Android 2.3.7 ROMs we fixed audio using some AOSP Alcatel .so files (to remove Samsung lib dependency) and some Samsung .so libraries too, this is the whole list:
# Samsung audio libs
acoustics.default.so
alsa.default.so
libaudiopolicy.so
# Alcatel audio libs
libaudio.so
libaudioflinger.so
libaudioeffect_jni.so
libmediaplayerservice.so

Our device uses ALSA audio system, which is also used on stock ROM. This is related to software more than hardware, although we are not planning at the momnt to "change" this audio way. To activate ALSA audio some changes need to be done on kernel, that samsung provide to us on their kernel sources. Mostly we need to enable ALSA on device .config file:
Code:
CONFIG_BRCM_SOUND_ALSA=y
CONFIG_BRCM_SOUND_ATHENA_ALSA=y
That's not an issue as prebuilt alsa libs work, so new libs should work too. Ramdisk needs some edit too, as ALSA audio system is stored on dev/snd, and this is well defined too on our ramdisk, ueventd.rc
Code:
/dev/snd/* 0660 system audio
We realised after that that actually CyanogenMod 7.2 Sources include ALSA lib sources, what we didn't know if those sources could work with our devices. This sources build the following libs, as releated to its Android.mk files:
We can found inside hardware/sound_alsa the following sources to build
libaudio
libaudioflinguer
hw/alsa.default
hw/acoustics.default
On external/alsa-lib we can found the sources of anoher lib
libasound
And apart from that, some other audio libs such as libaudiopolicy are built inside framework/base repository, but they doesn't make any conflict. Other libs are included on Android source files.
To enable the build of those libs, using ALSA software instead af "Android default (not sure about that)". I've enabled on Boardconfig.mk the following configs:
Code:
# Audio
BOARD_USES_GENERIC_AUDIO := false
BOARD_USES_ALSA_AUDIO := true
BOARD_PREBUILT_LIBAUDIO := false # even not writted.
BUILD_WITH_ALSA_UTILS := true
This configs enable the building of those libs on their Android.mk files.
Also, I've added on device_cooperve.mk the following lines to build those hw modules releated to audio:
Code:
# Audio
PRODUCT_PACKAGES += \
alsa.default \
acoustics.default
After the build finished, and fixed some errors, AUDIO WAS WORKING, but not as expected. There were issues on Audio Routing:
Headphones are detected through system, but audio is not reproduced on headphones (speakers does)
When you make a call, sometimes you can't and phone freezes, or when you hangout the call, phone freezes.
Everything else apart from that seems to be working, even microphone, although this bugs are pretty weird, I took a look to logcat.
Code:
[COLOR="Gray"]D/AndroidRuntime( 1419): CheckJNI is OFF
I/ ( 1420): ServiceManager: 0xad50[/COLOR]
[COLOR="Red"]E/ALSALib ( 1420): external/alsa-lib/src/control/control.c:882:(snd_ctl_open_noupdate) Invalid CTL AndroidOut[/COLOR]

I/AudioFlinger( 1420): AudioFlinger's thread 0x1d978 ready to run
D/ALSAModule( 1420): route called for devices 00000002 in mode 0...
I managed to fix those errors (E/) by moddifying asound.conf, found on system/etc, adding this lines on the top and deleting old ones:
Code:
ctl.AndroidOut {
type hw
card 0 # Can replace with drivers name from /proc/asound/cards
}
ctl.AndroidIn {
type hw
card 0
}
Now logcat shows this at the moment
Code:
[COLOR="Gray"]D/AndroidRuntime( 1425): CheckJNI is OFF

D/AudioHardwareALSA( 1426): openOutputStream called for devices: 0x00000002

Actually that's the actual logcat, using headphones, and sound goes through speakers:
Code:

We must take a look if that is kernel relevant or not, as we really need this libs to work, to then start working on CyanogenMod 9.1 / Android 4.0.4 audio. Any suggestions are welcomed, although if they are from newbie or developer, don't want this thread to be spammed as others

Why this is helpfull ?
Currently we based it upon cm7.2 GB
this is because our device uses to run GB as stock.
When we figure the sources out and figure out what is part 1 or such we can adapt and try to port to CM9 so in that we can have new libs aswell.
(W.I.P Post;P )

We are fixing on 2.3.7 at the moment. Tinyalsa gives support for msm8960 chips as I can see on their sources, so we should start from 2.3.7.

Biel already said in the op that he added /dev/snd in the Ramdisk and i dont think our device use tinyalsa because With Alsa Drivers biel got sound working.

No Way To Use Audio files from other devices
Not booting at all

Dear developers,
Considering Android 4.4.3 is now available in AOSP, when can we expect to get nightlies based on it?
Thanks!

Do not install this build directly to coolpad f2
you need to replace boot.img so yes porting is posssible

Just replace boot.img or something more? Could you port it or this is not so simple?

Q&A
Q : Why does it say Galaxy Tab S2 9.7 on Android File Host if this is for the 8.0 version ?
A : Android File Host doesn't feature the 8.0 version in their devices. Because of that, all is located under a folder called 8.0
Q : Why is everything so small?
A : The DPI rate is 320 which is the same as on the Stock rom. However, Samsung has made everything bigger. Since this is personal preference, you may always higher your DPI to make things bigger or lower your DPI to make things smaller under Settings > Display > DPI
Q : Will you ever work on CM13?
A : Yes, once we feel like CM12 is good enough, we will move to CM13

Great work!

Can't wait to use this once it reaches a point where it's functional for everyday use! Excellent work so far!

Good job man!!! Will test this as soon as the WiFi works

good news for all T810 users! @T_I is working on a port of my ROM. It came to the CM setup wizzard however had some problems with the touchscreen. Should hopefully be a easy fix.

So the sensor module just isn't loading.
Code:
I/ ( 3857): System server: starting sensor init.
D/SensorService( 3857): nuSensorService starting...
E/HAL ( 3857): load: module=/system/lib/hw/sensors.exynos5.so
E/SensorService( 3857): couldn't load sensors module (Invalid argument)
I/ ( 3857): System server: sensor init done.
Tried to use the note 4 ones. They did load up successfully but use different drivers.
Ex the gyroscope uses ICM20610 where mine uses LSM6DS3. I really only came this far. My nightmare would be to make my own sensor libs. That would mean that I would have to learn lot's of lot's of coding!

Sadly those are for the kernel.
However,
I found this open source sensor for the s3 I9300 that uses a , what I believe, older version of the gyro found in our device. I will see what I can decompile/reverse out of the current module for the tab and will compare it with the open source ones for the I9300. This will be hard and I would be very thankfull if you could redict any expierienced dev you know, here

Suprise!
Turns out I was just missing a shared libary. That caused the module not to load. Sooo.... all that s3 sensor work for nothing
Hey.... atleast I learned something.
Also, build will be released in about 1-2h

Nice! Good job mate!
Did you have time to look at wifi yet? I would love to try it if that works!

Ok so to wifi :
I know most of you want as number 1. priority a working WIFI connection, but this doesn't seem to be that easy to fix, at least not for my empty brain. As you've probably already noticed, my debugging skills are still quite bad (Yes I'm still learning... Yes I'm not perfect.... well maybe yes... ok no just kidding). The current issue i'm facing has probably to do something with the api drivers and wpa_supplicant. I've noticed that the KMSG doesn't even show a tiny trace of the cfg80211 driver and the nl80211 driver. If any developer out there knows what to do with the following log output when trying to access the wifi HAL / Enabling WIFI please tell me.

help me! please!

Reading through the error you will see that is is caused by Network on main thread exception.
In Android you are not allowed to do network calls on the main application thread. You need to use a separate AsyncTask. See this Stack Overflow thread.
