@wkpark... it is an important issue. It may be related to low mic sound in 
voice chat. During a voice chat in nimbuzz, I have to hold my phone as 
microphone keeping phone mic near mouth so that other can hear me....

why don't you attach your logcat/dmesg ?

this issue is almost nothing for me without logcat or dmesg.

In official froyo... Sound is very loud and clear in videos. Can we get help 
from that?

Original comment by iareh...@gmail.com on 7 Sep 2011 at 8:46

Ok. I see. the official firmware use "VOICE_RECORDER" device but GB use 
"SPEAKER" device as input device, strange.

so I just add the missing device "VOICE_RECORDER" in to the "libaudio.so" src 
with volume control and
set the right device as "VOICE_RECORDER".

now it works fine for me.

you have to restart your phone or adb shell killall mediaserver.

I restarted phone after copying file. Do I need killall command?? Can you 
confirm the file is new one?? :)

Original comment by iareh...@gmail.com on 7 Sep 2011 at 12:04

[GoogleCodeExporter]

you cant test like as following.

- try to record sound using the "Voice Recorder". it use the same input snd 
device used by camera app.

- compare with the unmodified libaudio.so and the new one.
  (you don't have to reboot. just 1) adb remount 2) adb push libaudio.so.old /system/lib/libaudio.so 3) adb shell killall mediaserver)

yes. same size but different md5sum.

No improvement. Better upload new system and boot images containing all new 
changes :)

I think you did not change the media volume.
you can change media volume with volume button when you are playing a sound 
file.

I have two phone, one is Official firmware and other is GB2.3.5.
so I can compare the difference, trust me~

I fully trust you. I have repeated procedure 5 times but results are same. May 
be i am doing something wrong. To me, it is enough to know that bug is resolved 
:)

hi husam... is new libaudio.so working fine for you??

Original comment by iareh...@gmail.com on 7 Sep 2011 at 5:07

I have found that sound is a bit louder using new libaudio.so but it is still 
quite low as compared to official froyo. Is there a parameter to adjust mic 
volume? attaching both files recorded using old and new libaudio

I did not mention about how much louder then old. yes. a little bit. somewhat 
smaller then expected.

the quality of sound produced by the Voice Recorder (or Camera app) is lower 
then expected.
so i think it is not a big problem now :)

I don't know how can i adjust mic volume now.
anyway I will check all other sound/fm-radio related issues with this issue.

cellphone, i think the volume of microphone must be upper than now

hi all , hi iareh . the file is working  , just do the following :

1-put the file libaudio.so  in the folder containing your adb program on your 
computre ( for me it is the c:\program files\android\android-sdk\tools )  
if you use android sdk program and dont find adb files in (tools ) folder then 
u have to download platform tools and u'll find adb files in it. 
if you use another adb program just put the libaudio.so file in the same folder
2-connect  the phone to the pc in debug mode
3- use this order to put the system folder in writable mode
adb shell mount -o remount rw /system

4- use this order to copy the new file from the pc to your phone :
 adb push libaudio.so /system/lib

5- reboot your phone .. 
 i did it and it improved the sound volume very much for both voice recorder and camera.
thank you wkp
