Trying to export a DV file that has 32kHz audio track fails

ffmpeg -hide_banner -f concat -safe 0 -protocol_whitelist file,pipe -i - -map 0:0 -c:0 copy -map 0:1 -c:1 copy -map 0:2 -c:2 copy -movflags +faststart -default_mode infer_no_subs -ignore_unknown -f dv -y file.dv
[dv @ 0x11ee04a60] Estimating duration from bitrate, this may be inaccurate
Input #0, concat, from 'pipe:':
  Duration: N/A, start: 0.000000, bitrate: 27048 kb/s
  Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn

[dv @ 0x11ef04f80] Can't initialize DV format!
Make sure that you supply exactly two streams:
     video: 25fps or 29.97fps, audio: 2ch/48|44|32kHz/PCM
     (50Mbps allows an optional second audio stream)
Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted
Error initializing output stream 0:2 -- 
Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:2 -> #0:2 (copy)

Looking at https://trac.ffmpeg.org/ticket/8352 - it seems that ffmpeg's implementation is incorrect.
