Default [Q] HTC snd7k tool

Hi dudes. I hope somebody can help me.

I had the Desire 500. And since i had the Phone, i had the Problem that the built-in Mic in whatsapp is not loud enough.

I try all the fixes what i found here and the Internet.

When i try add an pre-procces "agc" to the Audio.Source Default, after the reboot Sense launcher hangs and won`t start.

After Months now i have S-OFF because me was think that i can configure the sound in debug mode.

When i type in Terminal snd this i become:

i don`t find any Source how to config the HTC snd7k tool or how i boost the mic.

Can anybody help me
