encountered when installing Emacspeak. If there is a topic
that is not covered here, you should review the Emacspeak
mailing list archives at <A
HREF="http://www.cs.vassar.edu/~priestdo/emacspeak/"

You can find the answers to many additional questions there.

CLASS="COMMAND"
>The volume on my system is very low -
how can I increase it?</B
></DT
><DD
><P
> The easiest way to turn up
system volume is with a set of
speakers. However, sometimes
speakers aren't feasible (for
example, with a laptop), or
even with speakers, the
volume is still not loud
enough. In this case, you can
use the application
<SPAN
CLASS="APPLICATION"
>aumix</SPAN
>
to increase your system's volume.
</P
><P
> <SPAN
CLASS="APPLICATION"
>Aumix</SPAN
>
comes with many distributions
of Linux, but if your distro
doesn't have
<SPAN
CLASS="APPLICATION"
>aumix</SPAN
>,
you can download it from
<A
HREF="http://prdownloads.sourceforge.net/aumix/aumix-2.7.tar.gz"
TARGET="_top"
>http://prdownloads.sourceforge.net/aumix/aumix-2.7.tar.gz</A
>.
The latest version is 2.7.
</P
><P
> To use
<SPAN
CLASS="APPLICATION"
>aumix</SPAN
>
to increase your system's
volume, type the command
<B
CLASS="COMMAND"
>aumix -v
+100</B
> or
<B
CLASS="COMMAND"
>aumix -w +100</B
>. The numerical
value is the percentage
volume, so in this case 100
means 100%. You may want to
try different settings to find
the most comfortable one for
you.
</P
><P
> For more information on using
<SPAN
CLASS="APPLICATION"
>aumix</SPAN
>, type <B
CLASS="COMMAND"
>aumix
-h</B
> at the command prompt.

CLASS="COMMAND"
>sndconfig doesn't recognize my
soundcard. What should I do?</B
></DT
><DD
><P
> If sndconfig doesn't recognize
your soundcard, you should see
if you can
download a driver for your
card. The Advanced Linux
Sound Architecture (ALSA) web
site, located at <A
HREF="http://www.alsa-project.org"
TARGET="_top"
>http://www.alsa-project.org</A
>,
lists many sound
cards, along with their
drivers (if
available). Another alternative is
the Open Sound System (OSS)
for Linux. OSS is a
commercial implementation of
the Linux kernel drivers, and
a list of supported cards can
be found at <A
HREF="http://www.4front-tech.com/osshw.html"
TARGET="_top"
>http://www.4front-tech.com/osshw.html</A
>.
There used to be a free
version, but apparently it is
no longer available (if anyone
knows differently, please let
me know).

CLASS="COMMAND"
>When I try to install the ViaVoice RTK
rpm file, I get
the error "libXm.so.1 is missing." What's wrong?</B
></DT
><DD
><P
> The file
<TT
CLASS="FILENAME"
>libXm.so.1</TT
>
is part of the
<TT
CLASS="FILENAME"
>lesstif</TT
>
distribution, and it is also a
shared library. This error
message indicates that either
<TT
CLASS="FILENAME"
>lesstif</TT
>
is not installed, or that the
system is unable to locate the
file. Often shared libraries
are referenced by a
symbolic link to the real
shared library file, which may
be named something like
<TT
CLASS="FILENAME"
>libXm.so.1.0.17</TT
>.
When the name of the symbolic
link to the shared library and the
name of the real shared
library file differ,
the system may not be able to
find the shared library, even
if it exists. If another
program depends on a shared
library that cannot be found,
an error message like the one
above results. In the case of
<TT
CLASS="FILENAME"
>libXm.so.1</TT
>,
lesstif is only needed for
graphical demonstration
programs. Thus, if you do not
plan to use the graphical
mode, it is safe to install the
ViaVoice RTK rpm using the option
<B
CLASS="COMMAND"
>--nodeps</B
>,
which tells ViaVoice to ignore any
missing dependencies.

if you use any of the
ViaVoice voice recognition
software.

re-test tcl. If you are using
ViaVoice TTS as your
synthesizer, Emacspeak should

point. If you are using a
hardware synthesizer and you
still do not get any sound,
check to make
sure that the environment

correctly in your

</P

> The variable <TT
CLASS="VARNAME"
>DTK_PORT</TT

specifies which port your hardware
sythesizer is plugged into on
your computer. Under Linux, if
your synthesizer is plugged
into com1, you must set
<TT
CLASS="VARNAME"
>DTK_PORT</TT
> to
<TT
CLASS="FILENAME"
>/dev/ttyS0</TT

and if it is in com2, then
<TT

> If you have a hardware
synthesizer and are still not
getting any speech, you probably do
not have the necessary
permissions to use the serial
port for your
synthesizer. There are a
number of solutions to this
problem, and the best solution
depends on your operating
environment. For example, if you
are in a multi-user
environment, controlling the
access permissions to the
serial device may be a
concern. The options are as follows:
</P
><P
></P
><UL
><LI
STYLE="list-style-type: disc"
><P
> Change the
ownership of
the serail
device to the
user running
Emacspeak. To
do this, type
<B
CLASS="COMMAND"
>chown
<TT
CLASS="REPLACEABLE"
><I
>username</I
></TT
>
/dev/ttyS0</B
>
at the command
prompt,
then type
<B
CLASS="COMMAND"
>chmode
u+rw
/dev/ttyS0</B
>.
</P
></LI
><LI
STYLE="list-style-type: disc"
><P
> Add the user
to the group
associated
with the
serial
device. On Red
Hat systems
this is
usually the
group
<B
CLASS="COMMAND"
>tty</B
>.
To do this,
edit the
<TT
CLASS="FILENAME"
>/etc/group</TT
>
file and find
the line
starting with
<B
CLASS="COMMAND"
>tty:</B
>.
At the end of
that line, add
",<TT
CLASS="REPLACEABLE"
><I
>username</I
></TT
>"
where username
is your
username.
</P
></LI
><LI
STYLE="list-style-type: disc"
><P
> Give
read/write
access to the
serial device
for all
users. This is
the least
secure
solution, but
if you are the
only user on
the system, it
will not
matter. To
give
read/write
access, make
sure you are
the root user
and at the
command prompt
type
<B
CLASS="COMMAND"
>chmod
o+rw
/dev/ttyS0</B
