Hannah had this problem on an old Toshiba laptop. We found that possible
malware was involved, and I always had to tell her to go into Volume Control
and uncheck the mute all check box. Here's how I did it:
1. Press Windows+r to open the run dialogue box.
2. Assuming it gained focus, I got her to type sndvol32 (s n d v o l 32) and
press enter.
3. Assuming Volume Control gained focus, I got her to tab twice to the mute
all check box.
4. I got her to uncheck it.
In most cases, sound came back. However there were occasions where for some
unknown reason the sound didn't unmute.
This was with Windows XP Home, even with latest service packs and updates.
This thankfully hasn't happened as much on her Acer laptop running Vista
Home Premium. Should it mute itself, she's got USB speakers which act as an
external sound card. In the worst case she could press FN+F8 to unmute the
audio. Unfortunately this is specific to Acer, and is therefore not a
generic keyboard shortcut.
Just my £0.02.

Subject: [Blind-Computing] bad muting problem
We need some help; both my friend and I are blind; when on the computer,
all of a sudden we will loose speech, windows sounds and everything else
that one could hear; when we find someone that can see to look at the
screen we find that the computer has muted itself; we have two questions;
is there a way that a blind person can un/mute the computer; and secondly,
what would make the computer just decide to mute; any help in this mater
will be appreciated. Thanks,
Dan
