I have small program that captures audio from a microphone. As my microphone is very sensitive, I prefer to mute the microphone boost before capturing. I open alsamixer and set volume of the microphone boost to zero, save settings and exit. Then I execute my program. I see that it resets volume of the microphone boost in snd_pcm_hw_params. What should I do resolve this problem? Where can I find default value and change it?
What hardware and driver?
Basically the mic boost has nothing to do with the hw params setup, so it must be something else that clears the mic boost.
