Public bug reported:
Dear Developers,
In Ubuntu 10.04.3 release if an user booted with the live CD, default the live
system with following volum,e meters are default muted, I copyed amixer names:
'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.
I attaching two amixer text file, first file is showing the original
result, second shoving the results after I unchecked the mute checkbox
with GNOME Volume Control preference tool.
To easyest your work, I doed a diff output with two text file with diff -u
command, see the results:
