pulsesink: playback from WSL pipeline to Windows pulse server isn't smooth

No debugging was performed yet.

Environment

• Gstreamer pipeline: WSL with Ubuntu 18.04
• Windows 10 render server: x410 X-Windows server (https://token2shell.com/x410/) and PulseAudio for Windows

Issue

Video rendering works well but there is no audio output most of time (randomly I can hear sound)

Work around

pulsesink with provide-clock=FALSE (i.e, Using systemclock instead) shows no issue.
