 ffplay plays audio badly for one avi sample here because it fails
 detecting non-interleaved avi. This is a regression since ef8cc06d
 I will upload the sample, it is unfortunately very large.

 Every audio underrun is clearly audible, no problems with {{{ffmpeg}}}.

 Increasing the probesize makes the warning disappear but does not help
 with the audio problem.
