            Bug ID: 89158
           Summary: When testing a Skype installation (using Skype's Test
                    Call), there is no pavucontrol facility to specify
                    "Use webcam microphone". (default is 'builtin mic')

           Version: unspecified

Using:    pulseaudio-5.0-6    skype-4.3.0.37     on 64-bit Mageia-4 & -5

When testing a Skype installation (using Skype's Test Call) using a USB webcam,
there is no GUI facility to specify "Use webcam microphone". (Default is
'builtin mic')

Steps to Reproduce:

1. Install Skype. Connect. Select Menu/Options/Audio

2. Note that audio option 'Microphone' has only 1 option ("Pulseaudio")

3. In Pulseaudio Control (a.k.a. 'pavucontrol') note that webcam is shown 2nd
in 'Input Devices' list, but no means of specifying 'Use webcam mic' (although
if its volume button is moved to the right, any use of the webcam mic is
reflected in the 'blue line' meter.

4. Select 'Test Call' and speak into webcam mic.

5. Note that Skype plays back no audio.

N.B. The only way to select webcam mic seems to be to select it in the 
"Recording" section of pavucontrol, BUT if no recording is in progress 
then nothing appears in that section!   So must proceed as follows:

   (a) Open the pavucontrol 'Recording' section

   (b) Start a Test Call

   (c) In 'Recording' the default input source (builtin mic line) is now 
       shown.
          Click on that and a line appears showing the webcam info.

   (d) Click on the webcam info to set 'webcam mic' as the default input 
for Skype. (This appears to persist across later startups of Skype from 
then on.)

All that seems a bizarre hoop to have to jump through, and I have seen 
reports on the web of others who failed to find that clumsy workaround and so 
ditched pavucontrol altogether in favour of e.g. ALSA.

Suggested solutions:

   - In Audio options, allow 'webcam' to be selected in the Microphone line

OR:

 - In pavucontrol 'Input Devices' provide an option to select webcam mic.
