Description

Created attachment 372357
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.
