Public bug reported:
I bought a Logitech c310 webcam with a built in microphone which uses
pulse audio. I wanted to use it for skype calls. The camera is fine but
the pulse audio is completely unreliable. If I call the echo service, it
may or may not replay my voice with no reliable way to predict the
outcome.
First I found a problem with the sampling rate. My voice would sound
like Mickey Mouse. There is a solution to this problem:
sudo gedit /etc/pulse/daemon.conf
where I set a line in the file to
default-sample-rate = 16000
That solves the Mickey Mouse but something else is making it so
unreliable as to be useless. I noticed that when it fails the recording
level control fails to respond. I've included a screen shot where the
level control is working, but it can just as well fail to work. The
problem is not connected to skype because I can get the same reaction
from the sound recorder. If I ask the sound recorder to record my voice,
sometimes it will work and sometimes not. Again there seems to be the
same problem with the input level control - it will fail to respond.
The webcam is the only pulseaudio input device I have which I can test,
but I doubt it is really connected to the webcam. If there is anything I
can test from here, I would be happy to do so.
