!!!PLEASE WIPE BEFORE POSTING A BUG!!!

What steps will reproduce the problem?
Honestly have no idea, this happens every now and then.

What is the expected output? What do you see instead?
Mic to work during call. Mic does not work during call. This does get fixed 
after pressing the "Mute" button, then pressing the "Unmute" button (so the bug 
isn't major, just bringing it more to your attention)

What is the bin file you are using ? (0.010, 0.014, 0.016, 1.100...)
4.002.14.EMEA.GEN1

What version are you using ?
LCR-F 2.0

What patch or addons pack have you installed ?
Gingerbread Theme (w/o flip animations), 998MHz Overclock Kernel I have had 
this problem both before AND after using the Overclock kernel).

Where are stored your apps (phone/sd default is phone) ?
Ext2

Where is stored your dalvik-cache (phone/sd default is phone) ?
Ext2

Where are stored your datas (phone/sd default is phone) ?
Phone

Did you wipe dalvik ?
Yes. I believe this also fixes the issue sometimes without having to press 
mute+unmute

Did you wipe data (factory reset)
No

Please attach a log made with sendlog or log_debug tool (see wiki)
Cannot send a log right now the problem is gone as of right now.

Please provide any additional information below.
Mute+Unmute fixes the issue temporarily before it happens again.

I am having the same issue. I went to recovery mode every week and "move apps 
and dakvik cache". Aftera while it just happened.

By the way I applied original audio lib and OC kernel.

Switched to a different ROM (fear_4.008.08.EMEA.VFIT custom ROM by 
fear_factory) and the same thing happens. Now I don't think that this is an LCR 
thing and am wondering if this is at all hardware related or something which is 
in both kernels (apps2sd? fast dormancy?). Regardless, this might be a tough 
one to fix.

It might be dalvik-cache on sd. Never activated it, using only data/apps on sd 
ext2, I never had this mic issue.

Also check if you use any voip program, for example skype. It sometimes grab 
the mic and don't release it after a call. Skype for android is shit, dropped 
it in favor to fring..

I updated issue #166 for the same issue.

I can't remember having the same issue with the stock 2.1 ROM, and the only fix 
I found so far is to reboot the device. muting/unmuting during a call does not 
solve the issue, and got same issue using a bluetooth headset.

Seems other devices are affected by similar bugs...

Found someone who fixed his HTC by modifying the audofilter parameter files. 
http://forum.xda-developers.com/showthread.php?t=790873

Same fix could be adapted to the Acer ?

Checking my AudioFilter.csv file, and see it has "OB" (letter O) instead of 
"0B" (digit 0) as well. Thought this was already fixed in a previous release ?

I'll give it a try and change this....

Here's what I did :
Copy /etc/AudioFilter.csv to /sdcard, mount your device to the PC and edit the 
file (e.g. with notepad++) search for "OB" and replace with "0B" (without the 
quotes), save.

On the device, in a terminal :
su
cd /
mount -n -o remount,rw /system
mv /etc/AudioFilter.csv /etc/AudioFilter.old
cp /sdcard/AudioFilter.csv /etc
mount -n -o remount,ro /system

(maybe a reboot is needed ?)

I'll let you know if this fixed anything....

I forgot a 
chmod 644 /etc/AudioFilter.csv
before remounting /system in read only.

Just to let you know since I made this change, I have no more issues during 
calls with the mike level

Nice, hopefully this works. This bug is becoming quite annoying for me.

When I go into /etc in Root Explorer, I am unable to find an AudioFilter.csv 
file. Also when I search my phone using Root Explorer (searched for both 
AudioFileter.csv and AudioFilter), I still can't see it. Is it hidden somewhere?

I used "file expert" to copy file from /etc to sdcard, but you might as well 
use the "cp" shell command (terminal app).
