[CM7]echo problem SOLVED!!

---

today i tried to use GetRil in my thill 4G running BangL MOD(CM), GB v20c baseband


I installed the one read "lgp920-v21a-NOV ***" I think its safe because theres a restore option


after a reboot I tried to call my dad's phone, and use the speaker(this is where worst echo should happen)

and I yelled many time using my dad's phone, I couldn't hear a thing!
and the Thrill side can hear my voice (call quality has no problem.)



SO excited to share with everyone

Echo problem was the only thing that holding me back to the CM rom






Now It's solved!!




can any of ya test it out and confirm this works for everyone?

Gonna test today :)

How do you manage to solve the problem?
I'm trying new "CyanogenMod 7.2 Modded" and the sound in call as terrible echo( hear phones, speaker or loud speaker) .
Also play music in the speaker have very low sound.

strange today I tried to use my home phone to call my phone, and the echo is still there.



the low volume I think is because the voice is not coming from the speaker but from the top speaker, changing volume of media is setting should temporarily solve that, until you call someone.

cyanogen needs a lot of work..
One thing i discovered was that if i listened to the fm radio and somedody called me the audio modules crash and sound doesnt work.
