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

[JEBE]

Package: pavucontrol
Version: 2.0-2
Severity: normal

Dear Maintainer,

When using my laptop microphone (built-in or through a jack) the sound was very
low.

I tried to tune it through pavucontrol and couldn't. I tried to fix it through
alsamixer without success. At last there was no more sound. I purged and
reinstalled pulseaudio, gnome and pavucontrol without more success.

I found that muting mic and mic boost through alsamixer brought back low input
sound. I tried again to increase it through pavucontrol and found at last that
it can be increased up to 39 %. Over 39 % there is no more input signal and no
more capture.

39 % is just enough for normal use. But it is misleading and could be better.

Thank you very much for your attention.

Note - In order to be complete, maybe the jack microphone is not detected. I am
not sure, but I think it is not a linked issue and it is sure that increasing
the pavucontrol input volume mute any microphone.

Gnome release : 1:3.8+8
Pulseaudio : 5.0-13
Pavucontrol : 2.0-2
