Are you getting silence at all when this is happening? Or is it not
noticeable.
I ran into an issue with 14.4 where wasapisrc would play silence after a
period of time. The issue was potentially related to the internal audio
ringbuffer.
This is the bugzilla ticket I created on it:
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/806I eventually just worked around it by using directsoundsrc instead.
With buffer time set to 200000 and latency time to 50000, to avoid
similar issues with that element (they manifest after 10 minutes to 12
hours). Unfortunately you can't do that with wasapisrc because it
auto-calculates the latency.
