Yes, but only if the programs that want to play sound make their call
through artsd. If you've got a non-arts program that expects to drop
sound onto the /dev/dsp device file directly, it chucks a hissyfit
because artsd has already claimed it. (At least on my soundcard.)
Occasionally you can use artsdsp to fit things in, but not always.
