[Dev] [CM10] Fixing in call audio bug for CM10

---

The call issue of CM10 ROMs is present for some people. There will be a trouble when making a call each other could not hear voice or the other side would only hear big noise.
If you reboot the phone once a day (e.g. at the morning) it usually won't occur during the whole day, sometimes it will not fix the problem by reboot.

I checked the offical V30C and V28G radio logcat , and found it is differnet to the CM10 radio logcat.

you can verify this by

 adb logcat -b radio

when making a call.

The offical V28G logcat radio is something like this:

As you can see,
1. when the call start, the ril send
LGE_SET_CPATH 3
LGE_SET_CPATH 1 (if you make the call via headset, it will be LGE_SET_CPATH 2)
2. during the call session, the ril send
LGE_SET_CPATH 8
3. after ending the call , the ril send
LGE_SET_CPATH 0

so, I make a fix for the LGEInfineon.java(thank rmcc provide the original code, if I didn't remenber wrong...), try to simulate this command sequence in it(not very accu, but I think it will be OK).
you can put this file in your source tree “device/lge/star-common/ril/telephony/java/com/android/internal/telephony”, then rebuild the CM10 source.
Hope this can fix the CM10 call bug.

PS: lipisak built a CM10 here: http://forum.xda-developers.com/show...4&postcount=47
[WARNING]: I am not sure whether this fix will fix the audio bug or not, so it is a DEV test....

Another found : In V30C lge-ril.so, it used /dev/block/mmcblk0p5 as a datastorge for write_nvidia function, which will write IMEI, SWV, SWOV, INFO in it. But as CM partitions definition, /dev/block/mmcblk0p5 is used as boot.img....... I am not sure it will cause problem or not. But a dirty fix of lge-ril.so, which will use a hexeditor modified the binary code, would workaround this.
If in your logcat -b radio found these: write IMEI ok, write IMEI ng. write SWV ok, write SWV ng, write SWOV ok, write SWOV ng, write INFO ok, write INFO ng. then your boot.img would be corrupted.[Thank wkpark pointed out that In V30C, /dev/block/mmcblk0p5 is /misc not /data/ve, /dev/block/mmcblk0p10 is the /data/ve in V30C]

2012/11/29:
Fix MSC partition problem[PLEASE NOTE: THIS ASSUME YOU USE THE OLD GB BOOTLOADER & PARTITION, not OFFICIAL BOOTLOADER & PARTITION]
1. use the attached liblgeril.so, this is a quick fix in binary : mmcblk0p5=>mmcblk0p3
2. modified your kernel source code arch/arm/mach-tegra/lge/star/include/lge/board-star-nv.h

#ifdef CONFIG_CM_BOOTLOADER_COMPAT
#define LGE_NVDATA_PARTITION                    "/dev/block/mmcblk0p3"
#else
#define LGE_NVDATA_PARTITION                    "/dev/block/mmcblk0p5"
#endif

then recompile your kernel.
3. fix init.rc. modify the rild group id:

group radio cache inet misc audio sdcard_rw log system media_rw

4. fix uevent.tegra.rc, add a line at bottom:

/dev/block/mmcblk0p3      0660   system     radio

2012/12/04:
Found a temp fix for this, when you encounter the call bug, just reboot into recovery, do nothing, reboot. This will fix the phone for a while..

2012/12/07:
By compare linux 3.6.9 kernel source to V30C kernel source code, I found that the V30C kernel source wm8994.c has some bugs in it. There are a copy/paste bug and many "switch" "case" "break" mismatch bugs. I made a patch file to fix this. Goto your kernel source sound/soc/codes, input patch wm8994.c < wm8994.diff

2012/12/25:
Another fix for audio problem:
During the wm8994 suspend/resume , it use a unsafe version of read/write registers. I just modify the code , use a mutex lock protect version of register read/write.
Hope this can make some help.

https://github.com/marsgod/lge-kerne...99e7bb9d617236

I guess when an incoming call trigger, the wm8994 resume, it will take a long time 'restore' the wm8994 registers(because it use the I2C interface), if this process were interrupted by another read/write wm8994 attemp, it will cause problem.

2012/12/29:
Based on above patch, I built two kernel for P990 & SU660, as the attached files. Please have a try.
Just use CWM flash these zip files. The zip file will only update your kernel & modules, there is NO need make a factory reset or clean your cache/data.

EDIT: for P990 kernel , please check http://forum.xda-developers.com/show...&postcount=661

If this will work, you're my 'effin hero!

EDIT: Can somebody tell me where do I need to put the files more exactly? I searched for the location mentioned in the first post but couldn't find it...

Let the testing begin

this is was I'm talking about let´s see how it is a will five u my thanks just for u tried!

thought i'm the only one ...lol

No where. Its source code, need to be built with cm10 stuff.

Marsgod, why don't you write some notes into official repo for arcee?

Sent from my LG-P990 using xda app-developers app

can anyone rebuild cm10 with that?

i hope its work

As you can see the thread has a [DEV] in the title. Did ever cross your mind that if you don't know what to do with this file you are not addressed?

Building right now with the new LGEInfineon.java. Will test as soon as it's done

Thanks for this one !
