     GNOME version: ---

I'm using gstreamer 1.8 x86 on windows 10 and it uses 100% cpu of one core.
I tested 1.9.90 too.
The application is basically a playbin so I tried this command and got the same
result:

gst-launch-1.0.exe playbin uri="http://192.168.1.121:8000"

In the mailing list I was asked to provide a profiling result. this the two
first lines of the test showing that the cpu is used in libgstdirectsoundsink:

Function Name Total CPU (%) Self CPU (%) Total CPU (ms) Self CPU (ms) Module
- libgstdirectsoundsink.dll!0x00000067541cfe 61.45 % 0.22 % 3953 14
libgstdirectsoundsink.dll
[...]
+ libgstdirectsoundsink.dll!0x00000067541d15 22.31 % 0.19 % 1435 12
libgstdirectsoundsink.dll
