It gave a file size of 258822944 bytes. Almost 50 min:
  echo "258822944/(2*60*44100)" | bc -ql
48.90

This is the longest recording I have made on this hardware.

I have this running now:
+ arecord -B 200000 -F 100000 -c 1 -r 44100 -f S16 -M -D hw:0,0 -v arec.wav
Recording WAVE 'arec.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

Its setup is:
