Bug#766781: pavucontrol: Input volume cannot be more than 39%

[jbernon at free.fr]

Hi Felipe, 

My kernel has been updated since the first mail I sent. 
root at pc-jean-debian:/home/jean# uname -a 
Linux pc-jean-debian 3.16-3-amd64 #1 SMP Debian 3.16.5-1 (2014-10-10) x86_64 GNU/Linux 

The volume issue remains. 

"Element Front Mic Boost" "volume" is already "off". I tried to set "Element Mic Boost" "volume" from "merge" to "0". But it muted everything.

OK I just confirmed that this is desired behavior is pulseaudio, and 
that this is probably a bug in your driver. 

Pulseaudio by default "merges" the mic and mic boost controls into a 
single volume control. What is happening to you is that the boost 
control seems to be broken. 

Please try upgrading your kernel (your kernel was a few versions 
behind when you reported the bug). If that doesn't work out, we should 
reassign this bug to the kernel. 

As a workaround, you can try editing 
/usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf and 
inside the element [Element Front Mic Boost], set "volume = zero". 
That should disable merging of the two controls.
