no /dev/dsp Continued

[Lance Hoffmeyer <lanceh@ibm.net>]

Maybe I should rephrase the question here.  I have sound to some extent.  I can play *.wav files and CD's  from tcd.
A couple of apps will not work though. Timidity gives me an error of 'no /dev/dsp' and IBM's ViaVoice gives me the same
error.  I have performed a MAKEDEV /dev/audio in the /dev directory.  I have 'dsp', 'audio', and 'mixer' in the /dev directory.
How can I test that each of these work?

06:19:14 Buddha: /dev > ls audio
crw-rw----   1 root     audio     14,   4 Sep 13 20:33 audio
06:19:37 Buddha: /dev > ls mixer
crw-rw----   1 root     audio     14,   0 Sep 13 20:33 mixer
06:19:43 Buddha: /dev > ls dsp
crw-rw----   1 root     audio     14,   3 Sep 13 20:33 dsp

Do these file sizes look kind of small?
