Hy,

I played little this volume meters in terminal when I restarted the live CD.
Because the testing machine with I reported this bug are connected only 
two speakers, following amixer command resolves this problem:
amixer set 'LFE',0 on
After I ran this command, I begin hear Orca Screen Reader produced audio 
outputs.

I think this problem is an Alsa related issue, but I am not full sure.
If I would like making a patch for resolve this bug, how can I begin?

Difficultest me this problem fix and testing, because I am not always 
near this testing machine my work place. Usual I am working on my home, 
the distance the testing machine with I found this problem and my home 
is 68 KM.

My colleagues says me he's experiencing two other machines with similar 
problems, perhaps different soundcard chipset and different volume 
meters, Unfortunately when I tested this sound card not have enough time 
looking the two other computers.
If I going next time my working place for example a meeting or 
consultation, and testing the two other sound card, need reporting other 
volume meters related problems with separate bugs?

Attila

  Dear Developers,

  'Front',0
  'Surround',0
  'Center',0
  'LFE',0
  If I launch with GNOME Volume Control preference tool, mincreasing the output slider and uncheck the mute checkbox, the problem is resolved.
  Of course, this problem fixing is important for a11y related, because a screen reader user is important to default hear the screen reader audio output.
  I don't no yet this problem are present with newest Ubuntu releases this soundcard chipset, and I not often possible to use this machine with testing this problem.

  result, second shoving the results after I unchecked the mute checkbox
  with GNOME Volume Control preference tool.
