There may be more than one soundcard in the system. By accessing dsp0, =20
you hardcode the first detected soundcard. This may be not desired by =20
the user.
Either provide the possibility to specify a sound device, or use =20
'/dev/dsp', as this allows the user to set the default soundcard. He =20
can decide to route '/dev/dsp' to the second or third instead of the =20
first detected soundcard via a config mechanism. Here's the relevant =20
man page text:
---snip---
hw.snd.default_unit Default sound card for systems with
=09=09 multiple sound cards. When using
=09=09 devfs(5), the default device for
=09=09 /dev/dsp. Equivalent to a symlink from
=09=09 /dev/dsp to
=09=09 /dev/dsp${hw.snd.default_unit}.
hw.snd.default_auto Enable to automatically assign default
=09=09 sound unit to the most recent attached
=09=09 device.

Bye,
Alexander.

A good programmer is someone who looks both ways before crossing a
one-way street.
