[Bug 797329] Live Audio Playback from Microphone Goes Silent on Windows wasapi

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=797329

--- Comment #3 from Michael MacIntosh <mmacintosh at linear-systems.com> ---
using wasapisrc ! wasapisink sync=false doesn't work for me, it still goes
silent periodically, and usually when it starts this behavior, it will
eventually go silent permanently, usually in about 20 minutes sometimes longer
depending on hardware.

provide-clock=false on the wasapisrc sounds worse than the sync=false pipeline
for me.

slave-method=2 on the sink sounds fine at first, then after 90 seconds it goes
silent.

The silence appears to be caused by the ring buffer getting starved, which
might be related to the warning I am getting:
captured too many frames: have 448, want 447

However even in setups where it is not producing that error message, like:
wasapisrc use-audioclient3=true ! queue ! wasapisink
I still get the silence.  So I am assuming the warning message is a different
error.  Also the queue is load-bearing as without it you will get the message
"Can't record audio fast enough".
