Comment (by ddennedy):
I tried the following, and it produces a file with a lot of static noise
in addition to some discernible sounds (but no dialog) from having watched
the clip on Netflix and !YouTube.

I also tried without "-c copy" before that. Using "-c pcm_s24le" failed
with:

least a size of 18 was expected
