Can someone point me to some documentation on how to
use the /dev/dsp device under linux?
I understand that files sent to this device is digial
and will be converted to analog in the soundcard.
And am I correct that music encoded with MP3, OGG, and
similar, are decoded to the same "format" which can
be sent to the soundcard?

I wonder if I in a C program can write a music tune,
in an array or something, containing frequencies that
will be converted to analog in the soundcard.

Would rather not. /dev/dsp is a part of the old, deprecated OSS
API, while the ALSA api should be used instead nowadays.

See http://www.alsa-project.org/documentation.php#0.9doc

As a bonus, it may work on non-Linux systems too, since
they sometimes provide OSS emulation.
