Comment (by mushm0m):

 Two things I've noticed, unsure if significant, from the FFMPEG debug
 output I've shared:

 1. ALSA duration is reported as negative value - why?
 2. ALSA bitrate is reported as 3072kbps, which seems high (I only have a
 Pi Zero). Is this configurable? How do I figure out the ALSA bitrate my
 Arecord command is using, to see if they are different?
