I've got a robotic sound when using wasapi. It literally sounds like a robotic
speaking...

GST_DEBUG=3,wasapi:6 gst-launch-1.0.exe wasapisrc ! wasapisink

I also get the robotic sound with:

directsoundsrc ! audioconvert ! wasapisink

With this configuration:

wasapisrc ! audioconvert ! directsoundsrc

It's not robotic, it's just a periodic noise.

directsoundsrc ! directsoundsink works fine though.
