Comment (by MrNice):

 I did it again, copy/past of each command from comment 62 one after the
 other.
 after git checkout 3cac2f1, record was bad. No comment.
 after git checkout 743b389, record was what I could consider good even
 it's not perfect. Listen attached outffmpeg.wav:
 The first bip is longer, this is when the player loops => this is ok
 Just before the 4th bip there is a tic, same before the 6th, 11st 19th,
 and more

 For comparison I recorded with the command you gave previously;
 arecord -N -f cd -t wav out.wav
 This is perfect. Listen attached outarecord.wav

 I use a headphones to listen.
