Comment (by chconnor):

 Ah, sorry:

 {{{
 ffmpeg -f alsa -ac 2 -i hw:CARD=Cx231xxAudio,DEV=0 -c:a copy test-audio-
 only.avi
 }}}

  ...generates a broken file (with same "non-monotonic" errors). Stream is
 pcm wav.

 {{{
 ffmpeg -f alsa -ac 2 -i hw:CARD=Cx231xxAudio,DEV=0 -c:a copy test-audio-
 only.mkv
 }}}

  ...generates a working file with no errors reported (!) during capture.
 Stream is pcm wav.

 {{{
 ffmpeg -f alsa -ac 2 -i hw:CARD=Cx231xxAudio,DEV=0 -c:a copy test-audio-
 only.mov
 }}}

  ...generates a working file (with same "non-monotonic" errors). Stream is
 pcm wav.
