Here are two instances from CNN transcripts. Admittedly, the content
of the videos shown is not obvious. Please follow the links to obtain
more background information if this topic interests you.

but -- the Christmas tree was still up. I mean, everything --
everything we had and everything I owned is gone.

I have heard the phrase used several times over a period of years, but
it was used during a specific scenario (at least in the past). When
there were technical difficulties in obtaining an audio transmission
then the announcer would engage in some other activity.

When the technical obstructions were removed the announcer would
introduce the delayed segment with: "And now we have audio" or "And
now we have some sound for you". The video transmission would then
switch to the remote location or the video clip.

The existence of previous audio difficulties is not always obvious.
But I do not see evidence of audio difficulties in the transcripts of
these examples.
