[Gta04-owner] Extremely low microphone sensitivity

[Pong]

Hi List

At last I installed the GTA04 in a donor Freerunner, and everything
seems to be working fine. Except when I call my girlfriend, I scream
my guts out, but she can only hear a faint whisper. I have tried to
adjust everything with alsamixer during a call, and I can make echoes
(at both ends) and all sorts of psychedelic effects. The only thing
I can not produce is more volume. What do you think I should I do
about that?

Peter
