Yes, that works. In case anyone else reading this: cmd has to be
launched as admin or else you'll get error code 0x80070005.

I verified that it works with this pipeline (produces audio-feedback):
gst-launch-0.10 dshowaudiosrc device-name="Microfoon (Cirrus Logic
CS4206A" ! queue ! directsoundsink sync=false

For some reason autoaudiosink doesn't work here, but that's not an issue for me.

Thanks, my work is unstalled now.
