[Speex-dev] Noise suppression less than AGC gain

OK, I'll wait for your patch then ;-)

Well, I can change the defaults and then people with different setups
(e.g. no noise and low input volume) will ask me to change it the other
way... In the end, the only fix is to improve the AGC adaptation
decision, including (but not only) the VAD.
