Hi all,
I have a problem with custom ROMs runing on my Magic (32B). When I tried many ROMs I have a problem with microphone when make a call. The sound transmited from my phone to another is really quiet, and effect is similar to VoIP calls. When I don't speak other person hear just silance without noice from background. I know thak gsm modules have some options to enable echo cancelation and tune audio quality. Whan I come back to my orginal rom sound is good again.
Does anyone have the same problem?

Device info:
RADIO-22.22.19.26I
PVT 32B ENG S-OFF G
CPLD-10
HBOOT-1.33.2004 (SAPP10000)

I ran into the same issue. The problem is with 3 files from the /system/etc folder. AudioPreProcess.csv, AudioPara4.csv, and AudioFilter.csv.

I uploaded the files I pulled from a stock Rogers build. They sound perfect and work on any ROM.

The link is:

To install:
adb remount
adb push AudioPreProcess.csv /system/etc
adb push AudioPara4.csv /system/etc
adb push AudioFilter.csv /system/etc
adb shell reboot

After that you will be all good to go.

Am using Cyanogen 4.0.1 and the sound quality on call is clear, had a few issues with some hero roms, but i think the non-hero roms are not that bad with voice call clarity.

I was thinking about the same think but have no time to test it. These files you extracted form original rom ?

Yes I extracted them from an absolutely stock Rogers Magic. Also, its not a matter of testing. I used these files on 2 different magics. Works perfectly.

Are you using a 32b device?

Just to be clear: these files are already present in all the recent Cyanogen roms (I don't know on the others). This fix is just OLD!

I had the microphone problem using the Cyanogen 4.04 rom. The file AudioPara4.csv was wrong. I replaced it with the one from the zip and it works for me now.

Wow, that was a completely useless, unnecessary, and rude comment. Someone here is trying to help people that need it. If you aren't one of them, and you don't have a contribution, get lost.

I can confirm this

I confirm this problem, not with one but with several roms, new ones as well.

My phone is a magic 32B from spanish vodafone, and I have had to do the patch myself EVERY TIME.

I have not tried Hero roms, so I can not talk about those. And yes, the cyanogen are also affected by the problem.

Now, someone correctme but I thought that the sound patch V7 was a package for getting louder OUTPUT volume on the speaker, not to correct the microphone.

The audio hack is based on dreamn audio files,just like cyanogen and the other dream ported to sapphire/magic.and the mic level is alwais so low.
So we can only fix manually the audio files every time....Cheers
