Comment(by GNUtoo):

 with the test procedure at the beginning, speaker test still can't be ear
 after suspend,
 and here's the diff between step3 and step6:
 {{{

 +                       count 2
 +                       range '0 - 255'
 +               }
 +       }
  }
 }}}

 which is something normal under fso2 images(that's because of a software
 volume in /etc/asound.conf, which only appear after playing something).
