 Summary of the bug:

 libavcodec/utils.c
 In "av_get_exact_bits_per_sample" function,

 case AV_CODEC_ID_ADPCM_G722
 ...
     return 4;

 and

 libavformat/aiffdec.c
 In "get_aiff_header" function,

 if (!par->block_align)
     par->block_align = (av_get_bits_per_sample(par->codec_id) * channels)
 >> 3

 which output 0, causes

 C:\Users\user\Downloads>ffmpeg -i in.wav -c:a g722 out.afc -hide_banner
 Guessed Channel Layout for Input Stream #0.0 : stereo
 Input #0, wav, from 'in.wav':
