In-Call Audio Bug Fixed for CM10 on the LG Optimus 2X

The last time we brought you news about CyanogenMod 10 on the LG Optimus 2X, it was a patcher tool that fixed a myriad of issues. It helped CM10 fans fix a lot of issues with the ROM on the Optimus 2X, but it didn’t fix all of them. There is an audio bug during phone calls that prevents users from hearing people they’re talking to. Now, there may be a fix for it.

XDA Forum Member marsgod has released a patch that should fix the audio issue. As marsgod explains:

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).

Unlike most patches that are released to XDA, this one actually isn’t something you can flash. Developers building ROMs from source have to slip that LGEInfineon.java into their source before compiling. Thus, only a few people have given this a try. So far, those who have added it to their build have said the patch is working pretty well, but more testing is needed. To help users test it out, XDA Senior Member lipisak has compiled a quick, dirty build for users to test on their devices.
