<pre>Running Gentoo with pulseaudio version 5.0-r6.
Microphone is a logitech C525 webcam (usb audio).
I believe the problem started with PA 5, although I haven't tried downgrading
to PA 4.
The problem is that whenever the input volume is not exactly 100%, the sound
from the microphone is severely distorted with static/crackling. The VU meter
in pavucontrol will go all the way to max when this happens.
I have to set the volume to 100% both in the "input devices" as well as the
"recording" tabs in pavucontrol to make the microphone work. Once they are at
100% all static/distortion disappears and the microphone works normally.
My /etc/pulse/daemon.conf file is "stock" (I have not changed anything).
I have deleted any PA config in my home directory as well as logged in with a
new user to make sure it's not some left over config causing the problem.</pre>
