>The sound server only supports applications that are <SPAN
CLASS="APPLICATION"
>aRts</SPAN
>-aware.  Many
legacy applications want to access the sound device directly.  The
<B
CLASS="COMMAND"
>artsdsp</B
> command provides an interim solution that allows most
of these applications to run unchanged.</P
><P
>When an application is run under <SPAN
CLASS="APPLICATION"
>artsdsp</SPAN
> all
accesses to the <TT
CLASS="FILENAME"
>/dev/dsp</TT
> audio device are intercepted and
mapped into <SPAN
CLASS="APPLICATION"
>aRts</SPAN
> <SPAN
CLASS="ACRONYM"
>API</SPAN
> calls. While the device emulation is
not perfect, most applications work this way, albeit with some degradation in
performance and latency.</P
><P
>The <B
CLASS="COMMAND"
>artsdsp</B
> command follows the format:</P
><P

>Some applications work better with the <TT
CLASS="OPTION"
>--mmap</TT
> option. Not
all features of the sound device are fully emulated, but most applications
should work. If you find one that does not, submit a detailed bug report and the
developers may be able to fix it. Again, remember this is an interim solution
and something of an ugly hack; the best solution is to add native <SPAN
CLASS="APPLICATION"
>aRts</SPAN
> support
to the applications.  If your favorite sound application does not have <SPAN
CLASS="APPLICATION"
>aRts</SPAN
>
support, ask the developer to provide it.</P
