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

[jbernon at free.fr]

Hi Felipe, 

I tried your pactl command. The result is the same than through pavucontrol graphical tool. There is another puzzling feature : the decibel measure is negative. Below my pavucontrol screen. 
Thank you for your attention. Excuse my late answer, I was far from any computer this week.

Can you change the volume using pactl? 

pactl set-source-volume <source> 50% 

You can discover the source name with pactl list sources.
