Thanks for your answer. I am using the WinBuilds GPL package.

GraphEdit shows the name: "Microfoon (Cirrus Logic CS4206A" (without
the closing parenthesis). It is probably the correct name because if I
use another name I get a "device not found" error.

I suspect that there is something wrong with the DirectShow plugins
because I am also unable to produce my webcam using the dshowvideosrc
element, while ksvideosrc works fine.

Here are some details:

The dshowaudiosrc produces the "can't create dshow fakesink" error:
D:\gst-launch-0.10 dshowaudiosrc device-name="Microfoon (Cirrus Logic
CS4206A" ! audioconvert ! autoaudiosink
Setting pipeline to PAUSED ...

instance of the directshow fakesink (error=-2147221164)
ERROR: Pipeline doesn't want to pause.

The dshowvideosrc produces a similar error message:
D:\gst-launch-0.10 dshowvideosrc device-name="Built-in iSight" !
ffmpegcolorspace ! autovideosink
Setting pipeline to PAUSED ...
0:00:00.487000000  1304   00558F10 ERROR          dshowvideosrc

instance of our dshow fakesink filter (error=-2147221164)
ERROR: Pipeline doesn't want to pause.
Setting pipeline to NULL ...
Freeing pipeline ...


The ksvideosrc, using the same device-name, works fine:
D:\gst-launch-0.10 ksvideosrc device-name="Built-in iSight" !
ffmpegcolorspace ! autovideosink


Am I the only one experiencing this error?

Grts,
Francis
