I have the exact same porblem but +20 db boost already looks to be on in my asound.state file.
Code:
control.36 {
comment.access 'read write'
comment.type INTEGER
comment.range '0 - 31'
iface MIXER
name 'Mic Playback Volume'
value 31
}
control.37 {
comment.access 'read write'
comment.type BOOLEAN
iface MIXER
name 'Mic Boost (+20dB)'
value true
}
And my mic volume is jacked all the way up

. So what else can I do? I am perfectly loud coming out of my own speakers, everyone else says I am faint.
Thanks for any help.
