recording

Setup:

* Windows 7
* Not in a VM
* GStreamer 1.14.1 with the patches from bug 796280

I sometimes get crackling noise when using wasapisink. I can atm only reproduce
with Quod Libet and not with gst-play/gst-launch alone. Sometimes it works but
then starts the noise when I seek. I'll look if I can create a reproducer which
is self contained.

Attached is a sound sample, recorded using Audacity + wasapi loopback device.
It starts normally, after a few seconds I initiate a seek to about the same
position and then the noise starts.
