Comment (by varenc):

 For those struggling with the avfoundation audio stuttering issue, I
 resolved it just using the older ffmpeg 4.2-tessus to record.  That
 predates this ticket so clearly YMMV. Specifically I was getting audio
 stuttering with avfoundation only when using a virtual audio loopback
 device. (Loopback/Soundflower/etc)
