I have a C310 Logitech webcam and using some applications, other meeting participants complain that my audio sounds like that of a 'chipmunk'. After some googling the issue was identified to be the wrong sampling frequency identified by the camera.
$pacmd list-sources for this;
name :alsa_input.usb-046d_081b_2B075230-02.mono-fallback
sample spec: s16le 1ch 48000Hz
this must be set to 16000Hz in /etc/pulse/default.pa
load-module module-remap-source master=alsa_input.usb-046d_081b_2B075230-02.mono-fallback rate=16000
which will show a remapped device, like(from pavucontrol)
that should fix the issue.
